Calculated Fields Between Form And Subform
Jul 18, 2005
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!

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 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 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?

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.

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 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.

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

Hey Everyone,
I am stuck trying to figure out this problem. I have a main form "frm_tirelog_600" which has 4 combo boxes "cboleg",
"cbocar", "cbopos", "cboserial" on it. The first 3 combo boxes are used as criteria on 1 of 3 subforms that I have.
The fourth combo box "cboserial" is used for the criteria in a query on another subform that I have called "frm_mount_600_subform",
which is independant from the main form, I hope I have explained that clearly enough. What I need to be able to do is
have the subform fill in 3 of the fields on it "leg", "car", "pos" with the value from the 3 combo boxes on my main form. I
can get it to show in the fields but not write to the table. I have searched the forum and have not been able to locate anything
that would work and really need any assistance with this. Im not real strong in the coding department which is where I
beleive this could be done.
I have attached a copy of my DB which I hope will better explain it. Any help would be greatly appreciated

I have created a form with a subform and I want to subtract the total of the subform from the total of the form to get a balance; i.e. I have a total of expenses on the form and the subform is a record of payments against the expenses and I want to show a balance.
I have been all over this one and can not make the expression work. I have been working in Access for some time but this one has me stumped, I am probably over thinking it or just can't see the forest for the trees.
I have gone into the expression builder and created the formula but when I complete the process I get the #name? error statement in the field.
Can anyone help me with this problem? Thank you in advance. You can send responses to sharon.dunn@newmont.com.

I have a [Order Central table] that compiles products from four different categories that employees can order from.
Employees using the database will select from four categories on buttons which opens up the order form EX: [Category 1 form].
They enter their order info on [Category 1 form] into a subform sourced from [Category 1 Table] called [Category 1 subform].
Is there a way that they could select the "Category 1" button, which would run a macro opening [Category 1 form] with the [Category 1 subform] having a where condition of 1=0 (or just so that the subform appears blank)?

This is an employee timekeeping database. I have a main form "frmTEMain", with a tab subform named "frmGridsub" with a tab named "Grid" on the lower half. On the tab page is the "frmGridsub" a continuous form that looks like a datasheet, many horizontal rows of data. The subform works correctly with several combo boxes that auto populate. There are many different employees listed in the Grid subform. "Employee" is the name used for the field that holds the unique ID number in the tables that feed the subform. The subform populates another table "dbo_BCRC."
When I click on a row in the subform I want fields to update on the Main Form with Employee, LastName, FirstName, that come from the table that was populated when data was entered into the subform. As the person clicks on the various rows in the subform, the main form fields need to synch with the row.
Do I use "Got Focus" event? Do I need to create another subform and place it on the top half of the Main Form?
I can provide screen shots....

Hi,
I have read that it's not recommended to put calculated fields on a table and they should instead be calculated using a query.
How about if I need to store that calculated value in a table (e.g. field1 + field2 = value in field3)
How can I do that please?
Thanks,
B

I am trying to create a calculated field in a query, that shows money owed from customers. I have 4 different job codes that have their own prices. I also have customers with the amount of hours they owe for, for each job. There are two customers that owe for two different jobs. I know how to write in : Money Owed: [price per hour]*[number of hours]. but i want to have only one line for each customer when i run the query. How do i combine??

I have a detail form, which has controls populated from a query.
For example,
Name Number
xxxx xxxx
This can be any length depending upon the amount of database records, so there might be 5 names, or 4 names, etc.
I then need to sum these in the footer. Is the possible?
I just seem to get #Error displayed when doing SUM([ControlBoxName])

I have a calculated text box on a form:-
=[AnnualSavings]/[SKUAnnualSpendInPounds]*100
But, if both the Annual Savings and SKUAnnualSpendInPounds text boxes have a value of 0 the result of the calulation comes out as #Num!. I assume this is the error because I am doing 0 divided by 0.
Does anyone know if this is the reason for my error and if so is there anyway of changing the #Num! back into a 0 so that I can submit it to my tables.
Any help would be greatly appreciated

I have an invoice form named frmInvoice. It contains a subform named subInvDetails. I am trying unsuccessfully to transfer a calculated subtotal from a text box in subInvDetails to a total in a text box in frmInvoice. Is there a way to do this? I have tried everything I can think of but I can't seem to make it happen.
To be more precise, I have a textbox which is a calculated value ([Rate]*[Hours]) named txtSubTotal in the sub form. In the main form I have a field named txtTotal. I thought that setting the Default Value of txtTotal to =Sum([Forms]![subInvDetail]![Subtotal]) was the right way to it, but the value of txtTotal remained zero. I have also tried using =Sum([Forms]![subInvDetail]![Subtotal]) as txtTotal's Control Source, but that didn't fit my needs or seem like the right way to do it. It didn't work anyway.

I developed a query that calulates when a contract is reviewed i.e 5 weeks and 9 weeks after the commencement date. These are called CDE1 and CDE2. This works well and the CDE1 and CDE2 dates are displayed ok.
The query above is:
SELECT Contract.ContractNo, Contract.APSNo, Contract.Firstname, Contract.Surname, Contract.AgencyDesc, Contract.FacilityName, Contract.Designation, Contract.WeeklyHrs, Contract.PositionNo, Contract.ComDate, Contract.EndDate, IIf(DateAdd("ww",5,[comdate])<[enddate],DateAdd("ww",5,[comdate])) AS 1stCDE, IIf(DateAdd("ww",9,[comdate])<[enddate],DateAdd("ww",9,[comdate])) AS 2ndCDE
FROM Contract;
The problem is that I now want to access contracts under these CDE dates between two dates that is user defined (startdate) and (enddate).
As the above are calculated fields, how can I develop a new query based on the above as CDE1 and CDE2 are already calculated fields?

New to Access and learning the hard way. Im sure this is an easy one, but sure would appreciate the help. I am trying to sum a group of cells and display the total, which i have done. But I also want to store this total in my database. So my question is, how do i move my calculated total to my field that has the "record source" bound back to my field in the database? Hope that makes sense. Thanks in advance.

I have an Access 97 database with a form and a subform for invoice and invoice details. When I change the qty or price in the subform I have a calculated field on the main form that updates. I also have a button that when clicked brings up the payment screen with the totals from the previous screen. The problem lies when I change the qty or price and click the button right away, the next form pops up but does not take the new totals, it grabs the old ones. The calculated fields do not refresh fast enough. I have tried requery, refresh, and even a loop to make it wait before opening the payment form, but nothing seems to work. I'm at a loss. Any ideas would be appreciated
Thanks

Now I can create a Query that adds, subtracts a specific column, but im having a hard time trying to get the information into a form since it don't seem to allow me to pick the query field which is calculated as a datasource. Can someone tell me how to make a calculated query column appear on a form as a field? Such if I type in monday in the regular table, the form will add a few days to the next available game? I have the information/code already in a query that displays the query right in a new table using the Expr method but I can't get the form to just simply display the field. Someone please help!
I see a few people asked close to the same question but nobody never answered so I am thinking it is impossible

I keep getting caught up in the same point over and over again. I need to save a calculated field's calculation to a table field. The problem is how do I do this? I already know about the rules but I need to do this and store that specific information. Can someone post a sample code? The problem is the code and codes I been using dont' seem to work any more. I was putting
fieldname = textbox2.txt
in the form before update box. The problem with that is it would give me an error if the data source the calculation pulls from is not in the table/form.
