I have a form created from a table and I had to use calculations in some of the fields to automate certain processes. Now, if I pull a report based on the fields in the table - I am getting all except for the fields with the calculations. Is there any way to update the main table - since most of the calculations were done with text boxes?
View RepliesI've read over and over that calculated data is bad, that's fine with me... but here is my dillema...
I have four fields that interact with my calculation in a single form. There is only one table in the database.
AmountF (The stored data in the table) (amount financed)
FC (calculated by =[amountf]*.25) (finance charge)
Amount Paid (used in calculation of total due)
total due (calculated by =[amountf]+[fc]-[amount paid])
The math already works, everything works. I can choose to print the form and it looks great. However, I would like for it to (when I'm done printing the form) somehow save the total due data to the AmountF column in the table. AmountF is in the same line as all the other information, so I would like it to not create a new record just update the old one.
All four of these fields have a text box in the form for themselves.
Is there a way to make some of the fields from my form that contain calculated values carry to the table? Right now the values calculate correctly in the form but when I look at the table the field is blank...
I was hoping to use one form to calculate a value, insert it in the table, and then use that value in another form.
:rolleyes:
Please help! I am a newbie and VERY confused. I am not a programmer but am just learning so any help much appreciated! I'm not even sure if I've posted this to the right place?
I have so far created a table and also an asscoiated form - they both work! Changes in the form go into the table, no problem EXCEPT where I have a calculated field in the form - this info doesnt go into the table - how do I get this information to go back into the table?
I am trying to do this because I want to include the result of the calculated fields in a mail merge letter in Word (and Word wont pick up fields from my associated form - only from the table or from a query!)
Please rescue a damsel in definite distress (I've been knocking my head against a brick wall on this for 3 hours now!)
Many thanks in advance :D
We have our access database with a bit of a messy structure?
We use our database to record sizes of our product. I am hoping to improve it by adding the items we have in stock to prevent manufacturing more.
Basically our main database called "Make & Model 1" has a list of various makes and model numbers, each model number lists various information needed to manufacture a replacement part.
Customers order the part and these part details are entered into a table called "Order Detail" What I would like to happen is that when the details are entered a calculated field adds the data entered to a text string. I need to match the text string to the same text string in a table called "stock" as there could be one part that matches hundreds of models.
Basically the "profile" "Colour" "height" and "width" make the string and this is what I need to match and tick a box / populate the number of items in stock. Eventually I would like this to reduce by the amount ordered but lets do one step at a time.
I am using Access 2010
I have 6 text box on the form which are unbound. Now we enter the entry in these boxes then I have update button on the form to update the record in table. all fields should be clear after update the records in table so I can enter the new entry.
I am using ms access 2007. Is there any liberary to add?
Form fields
text1
text2
text3
text4
text5
text6
Table fields
emp_id
batchid
training_name
training_hour
start_date
end_date
I have a textbox on a form that displays a calculated number with regards to input from other text boxes.
I need this calculated number to update to a corresponding field within a table.
I have a button that updates the information, but the calculated field will not update.
I have an "=" expression written that does all of the calculating. When I put this in the 'control source' it calculates and displays on the form perfectly, but will not update the table. If I change the control source to the field within the table and then move the "=" statement/expression someplace else....the field is blank on the form, but I can manually input a number and it will update to the table.

I have a login form with a combobox which derives its list of values from an EmployeeRecord table (i.e., last name, first name, securityID, job grade and record number): only the last name and first name appear in the list. (I swiped some VB code for a multiuser login form and routine from several previous posts.)
After it performs the security validation/authorization, it then opens a navigation control form based upon the user's job grade. It runs after the click button event. To this I would like to update another table, LoginEvent, with the last name, first name and record number from the combobox selection, and also add the time and date of the click.
I know that it is bad form to store a calculated field in a table - normalization and all that - but I can see no other way around a need that I have.
I'm trying to make a database to store injury time for employees. If an employee is injured, he can do light work for a certain amount of time, but this light work need not be contiguous. But, the total time on light work must be known so as to see when it is used up.
For example:
Bob is injured on 4/1/06 and goes on light work on 4/2/06 until 4/5/06 (4 days). Bob is then taken off light work until 4/10/06 when he reinjures the same injury. This does not count as a new injury, because it is an aggravation of the old one. So, Bob goes back on light work on 4/10/06 until 4/15/06 (6 days).
So, I need to store Bob's total time on light work for this injury (10 days) so that I can keep a running total to check against the maximum for a single injury. All I can think of is to store the sum of days on light work as a field in Bob's injury record, but that means storing a calculated field in a table.
Am I missing an easy way to do this, or is there a method to do what I want that I am just not aware of?
Thanx for any help!
I have a small Database that produces invoices, Each invoice could have 5 items on it which are compeleted at different Dates. (cutting hair in an OAP Home) Invoice to be produced at the end of each month which shows what happened each week. This will be generated for each person in the home. I can display all the information in a form when inputing the invoice information. I want a button to copy the invoice number the client name and the total of the invoice to a new table. The total of the invoice is calculated control on the form.
How do I do this??? can anyone help
I need a total in a table to substract payments from.
All Help will be much appreciated.
Hi all,
I need to figure out how to have two calculated fields written to the database table instead of just being displayed in the form.
The user selects a number from 1 to 5 in the first field, and a number from 1 to 7 in the second field. The first calculating field multiplies these two numbers and displays the result. The second calculating field determines where the resulting number fits in three ranges of numbers and displays the result as Low, Medium, Or High.
My problem is the calculated results are be displayed in the form but not being written to the table. I cannot create a report to display all the High results, etc.
How do I update the calculation field formula to write the results into the table so I can create queries/reports on the calculated data?
Thanks,

I have three columns where A is a number, B is a number and I want to make C = to the greater of the two. i.e.
Col A = 10, Col B = 12 therefore Column C = Col B or Col A = 12, Col B = 10 therefore Col C = Col A
I need to display a value from a table in a text field on a form based on another text field on the same form.
The table has records as follows:
Month/Year xx Month No xx Year No xx Month ID (xx shows break in columns)
Jan-06 xx 1 xx 2006 xx 24
Feb-06 xx 2 xx 2006 xx 25
Mar-06 xx 3 xx 2006 xx 26
Apr-06 xx 4 xx 2006 xx 27
May-06 xx 5 xx 2006 xx 28
Jun-06 xx 6 xx 2006 xx 29
Jul-06 xx 7 xx 2006 xx 30
In one text field I use the DateSerial function to calculate the value of the previous month (e.g.Jul-06). I need to return the MonthID value to the second text field based on the value stored against it is the table, so in case of Jul-06 it would show 30 in text field 2.
I am great with Excel but not soo much with Access 2010. I Excel, what I needed to do was very simple but duplicating what I did in Access is not soo easy.I am trying to calculate billings for FSA & HRA. I have set up one table with all the data. I want to add columns to the table to calculate:
1. Is there an account balance-excel formula:
2. If the account is still active
3. If the plan year run out is "active runout" or "runout over"
4. calculate each account type with a rate *count of FSA accounts = total to bill
Here are my excel formulas that for the life of me I can't get to work.
Account balance==IF(V2="HCRA",(IF(AB2-AD2>0,"Available Balance",IF(AB2-AD2=0,"Zero Balance","Negative Balance"))),((IF(AC2-AD2>0,"Available Balance",IF(AC2-AD2=0,"Zero Balance","Negative Balance")))))
Active runout/runout over=
=IF(AG2="YES","Active Runout",(IF(S2=W2,(IF(AF2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")),(IF(AE2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")))))
Active account=
=IF(D2<$AJ$1,"NO",IF(W2>$AJ$1,IF(S2=W2,"YES","NO") ,"NO"))
Can I have calculated fields that refer back to a calculated field?
I know that it isn't usually best practise to store calculated fields in a table, but in my situation it is necessary, and I haven't really found a good answer for this after searching these and other forums.
Currently my database has one "Name" field (I didn't make it like this) which might look like this "Jonathan (John) Smith"
Now I also have reason to grab the name like this "Smith, John" for other purposes.
I've set up a form for inputting new people with separate fields for firstname, preferredname, and lastname. I have the calculated fields:
=[fname] & " (" & [pname] & ") " & [lname]
=[lname] & ", " & [pname]
(Later I will add in all the iif's for if there is no preferred name)
Upon finishing the form, the user hits Submit, and I would like to store the concatenated values into the table in their appropriate fields.
I can do this with a SQL INSERT INTO statement but I'd have to add all 25 or so fields from the form, and injecting user input directly into a SQL statement is not best practice either.
How to store a calculated field into a table
I am preparing an invoice and I have a field called deposit .Now this field calculates %40 of the total of the order .but if the user wishes they can enter what they like .Now this field must be stored in a table for ever and a day and must not change or the invoice will be useless .I can see no other way of doing this and my research tells me (allen Brown) that this is sometimes necessary .
Could someone tell me what Event I need to put this code in to calculate my fields when the form first opens?
I have this code on both the After Update and On Change events which is working fine, but, when I first open the form, those calculated fields are blank and I have to perform a change or update before the calculations will appear each time.
If Not IsNull(Me.fcstloc) Then
Me.prodvolume = DSum("[volume]", "qryMonthlyEngineVolumes", "[product] = '" & Forms!Projects!product & "'" & " And [MonthID] Between " & Forms!Projects.MonthID.Column(0) & " And 12")
ElseIf Not IsNull(Me.prodvolume) Then
Me.prodvolume = DLookup("[2004volume]", "tblProjectDetails", "[projectid] = " & Forms!Projects!projectid & "")
End If
Thanks!

I have an Invoice Form with a Payments Subform. Here are the details:
frmInvoice
InvoiceID
Customer
ShipmentID
QtyShipped
UnitPrice
frmPaymentsSubform
PaymentID
InvoiceID
CheckNum
DateReceived
Amount
An invoice can be paid in multiple payments. (One-to-Many Relationship).
I have a calculated field that takes QtyShipped * UnitPrice, which gives me my total due. That works correctly. However, I want to have another calculated field that sums all of the payments (the Amount field). Then I want another field that takes the difference between the total due and the sum of all the payments, and gives me a Remaining Due calculated field.
Right now, my TotalPaid and TotalRemaining fields are marked with '#Error'. Is that because TotalPaid is a running sum? Every day I can go in and add a payment to an invoice, so the number would be constantly changing until it was paid in full.
Any suggestions would be great!
I have a form where the record source is a table.The form has about 5 calculated fields on it. The screen flickers quite badly and at the bottom says calculating. Sometimes the database locks up.
To stop this flickering i created a query so that the calculations are done in the query. Then i linked the form to the query instead of the table. Am i doing this correctly as i didn't think the table would show any new data that i entered into the form but it does seem to work. Is it because i am only using one table.
I am using Access 2003.
I have a subform embedded in a main form, the subform has a field (text box) that is doing automatic calculation so no manual entries are needed from the user. I have tried to pass automatically the final result to a text box in the main form, but all events are not working (afterupdate, On change, On Dirty), etc.
I have a button to do the above mentioned in the main form, but I don’t want to use that button, I want to do all the process from the subform.
Also, from the subform I was able to do click on the button on the main form (programmatically), however MS Access is too quick and the value extracted from the subform is always empty (zero); Acees is finishing before the calculation is done.
I am using MS Access 2010.
I have a calculated field that shows the sum of two other fields on the same form. I've got as far as making the expression work but it doesn't quite do what I want. I need the calculated field to update when any one of the reference fields are updated (i.e. currently it only updates once all the fields in the expression are updated).
How to I change the form so that the calculated field updates based on current values (including any fields that contain no value)?
I don't have any database experience whatsoever so please go easy.
I'm guessing this kind of this is extremely simple for all of you.
I'm constructing a database of network resources and devices and I'd like to automatically update the values in one field based on the values of a field in another table.
The first table is called "IP" and the fields are called "Address", "IP Type" and "Device".
The second table is called "Devices" and contains the fields "Name", "Description", "Asset Number" and "IP".
Here's an example of the tables: (ignore the "code" tag. i've only used it to align my columns properly)
DEVICES:
NameDescriptionAssetIP
XserveFile Server107203.30.144.75
ProliantXDHCP119203.30.144.15
IP:
AddressIP TypeDevice
203.30.144.75Static
203.30.144.15Static
What I want is for the Device field in the IP table to automatically update it's values based on the values found in the Devices table. In this case, the values that should appear in the Device field in the IP table are "Xserve" and "ProliantX".
I've searched through but haven't found a complete solution, just little pieces which I'm too inexperienced to put together myself.
thank you

I have a copy of the back-end that gets a search key error 3709 on two records. In other words, I can duplicate the problem.
The interesting part is that I can update any other field on both these records and save the record, but when I try to change two specific fields, I get a Search Key Error and have to ESC out to continue (basically UNDO the change). Both fields are text fields with lengths of 7 characters and 255 characters, and both are COMBO Boxes on the form.
I tried to focus on the form think there was an issue in the code. I can definitely TRAP the 3709 error on the ON ERROR event on the form using "if dataerr = 3709", but then I tried something even simplier.
I went directly to the table and to each of the records. Again I can update any other field in the record but these two specific fields. When I try to change either of them and move to another record, you get a Search Key Error 3709.
By going to the table record directly I'm as low level as I can get. There are no validation rules on either field at the database level. If it was truly CORRUPT would it let me update any of the other fields on either of these records? One is an empid (not a primary key but is indexed with duplicates okay and not required), and one is status code (not a primary key but is indexed with duplicates okay and not required) so they're no critical fields, but something is keeping them from CHANGING.
Just tried something else; deleted the INDEXES on both the fields. Now it works! I am completely confused now because it really wasn't a corrupt record, but the indexes are causing the problem. Do I need to update the indexes somehow when the users selects a new empid or status code?
I would like to achieve the following task described below:
Just for an example i have two tables = Table1 and Table2
Table1 contains following fields: ID , CusName, Price , Date_
Table2 Contains following fields: ID, CusName, Price, Date_
I would like to update Price and Date Field of Table 1 where Table 1 ID matching with Table 2 and Table 2 Date is maximum(most recent date).
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
Hello,
I have been reading various threads about this subject and I know that one shouldn't store a calculated field in a table.
I believe this may be an exception to the rule (but I could be wrong).
I am making a pricing database that will use a few manual inputs and the rest of the fields will be calculations (gross/profit margin, expenses) based off these inputs. We need to have these calcuated fields stored because they are essential to the pricing decisions and we will have to go back and access these fields at a later time. Another reason for this is because there will be at least one report that will be used to compare prices and calculated fields associated to a certain product by company, program, item type, ect...
Any help would be greatly appreciated.
