Calculated Field That Shows Sum Of Two Other Fields On Same Form
Feb 12, 2013
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 created a form with combo box which shows certain fields I selected. By clicking that I want to open a NEW form which has all the fields so that I can edit the record.
I have 4 texts fields [DEVICE INSTALL] , [INSTRUMENT STAND], [BRACKETS RACEWAY SUPPORTS], [TUBING CAPILLARY] all can be either a percentage from 1-100 or "N/A" except [DEVICE INSTALL].I would like to calculate the [percentage complete]
my calculation in the field is as follows: ([DEVICE INSTALL]+ IIf([INSTRUMENT STAND]="N/A",100,[INSTRUMENT STAND])+ IIf([TUBING CAPILLARY]="N/A",100,[TUBING CAPILLARY])+ IIf([BRACKETS RACEWAY SUPPORTS]="N/A",100,[BRACKETS RACEWAY SUPPORTS])) /4
this seems to work to a degree. but for some reason when the [INSTRUMENT STAND] value is not "N/A" the percentage calculated is a wacky value much higher than 100. how could I possibly change my division #?
In my database main form with subform. subform have query as recordsource.total of one of field in subform shown on main form. all is ok and show total correctly but when subform have no records then total field on main form shows #error. How to convert this value either into null string or zero(0).
I am trying to get an average from several numbered fields, which some may occasionally be blank.
=Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0)
I get an error message that says "The expression =Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0) cannot be used in a calculated column. This is a hypothetical expression being used.
The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?
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
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.
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 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.
: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!)
Having a real brain cramp with this one, so any detailed help would be appreciated:
On a form, I have one bound field that I want to use for calculations - ThirdCompTime. ThirdCompTime needs to calculate the difference between two bound date fields (ThirdTimeIn and ThirdTimeOut) and display the result.
I tried to build an expression to do this:
=[ThirdTimeOut]-[ThirdTimeIn]
but I cannot get the results to display. The two date fields' formats are set as General Date and the calculated field's format is set as Long Integar number. Any ideas?
I am trying to run graph on a report from query but what's happening is query shows name but report on graph shows ID'S of the field .
Below is my query
SELECT tblMainTWTTPSheet.txtRootCause, Count(tblMainTWTTPSheet.txtRootCause) AS CountOftxtRootCause FROM tblMainTWTTPSheet GROUP BY tblMainTWTTPSheet.txtRootCause, tblMainTWTTPSheet.Date HAVING (((tblMainTWTTPSheet.txtRootCause) Is Not Null) AND ((Count(tblMainTWTTPSheet.txtRootCause)) Is Not Null) AND ((tblMainTWTTPSheet.Date) Between [Forms]![frmStratificationOfRootCauses]![startDate] And [Forms]![frmStratificationOfRootCauses]![endDate]));
My bound column on main menu form and back end table is 1
Hi all, I have a Form which calculates how much to charge a client.
I have a "Fee" field, and a few calculated fields based on this fee. The calculated field I'm having problems with is the "Tax" Field.
Prior to July 1, 2006, i had no problems. The tax was basically " =[Fee]*.07 " in the "control source" under the properties of the field i created in the form.
After July 1, the tax just went down (in Canada) to 6%. I can just simply change the control source to =[Fee]*.06 ...however, when I do this, the form also changes all the clients before July 1 to a tax rate of 6% as well...I'm not good with coding, and an not sure how to make the calculated field in the form to change the tax rate to 6% only if the client's contact date is after July 1, 2006. ContactDate is also another field in this form.
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...
Hi. I have an Order form that is based on an Order table. In this form there are also a number of text boxes (not bound to table) with calculations, and one final text box with a deadline based on these calculations. Is it possible to filter this form based on the deadline? I can do this by making the form based on a query, but then again I'm not able to edit the information in the form.... Please anyone???
I have a form which calculates alot of numbers. Im trying to figure out how to save the calculation to a table field. Is this possible? Can someone help me with a solution please
I have a main form with several with four subforms. On the main form I have a bound text box [ShiftTotal] I have on each subform a unbound text box that sums a field [ExtTaxIn]. I am working with just one subform till I can get it to work correctly. The code I am using on the after update event is as follows.
So i have a Calculated field in a table which is an expiration date. It adds two years to another field. Both field are on a Form. make the calculated field editable because some of the expiry dates are not necessarily 2 years. How do i change this?? do i need to like code it? i have no clue how to even start.
I have a form with three fields named 'quantity' (numberfield), 'service' (combo box) and 'amount' (calculated field with controlsource =[service].[Column](2)*[quantity].
I try to sum the amount field in the formfooter with =Sum([service].[Column](2)*[quantity]) but I receive an error.
Somehow it does not get the value for [service].[Column](2)
I am working with access forms, but I am having a problem when I try to calculate fields. I have three text box:
Quantity Price Total
When I type numbers in quantity and price field the Total field should get populated with the total of Quantity and Prices..I have tried a lot of formulas like:
=[Quantity]*[Price] But nothing happens when I put the form in Form View. In the Total field I get #Error.
I am working on a report and have found a problem. I have a field called "region". The data is geographical and is basically stuff like "southeast", "mid-atlantic", "southwest", etc. I reference this field in the report but the report shows the ID field of the table where this data exists, rather than the data in the "region" field. So, instead of "southeast", it shows "3".
I have a report with a calculated field. This calculated field needs to pull the value or total from a field in another report. I think the formula is : =([AssmntC].Reports!totalreqamnt4) but I'm getting ?Name as the result. The report is AssmntB where I need to have the value copied. The original report is AssmntC and the field is totalreqamnt4 where the value is originally calculated. totalreqmant4 is also a calculated field which sums fields from a query.
Basically i have a form where i get info from multiple tables. On the main form itself i have 3 calculated fields for hours where i add all the hours i choose (from a subform) onto the main form.
My issue is i can create a query to come up with all the fields for my report, but how do i get the calculated fields on my main form on the report? Is there a way to print the calculated fields on the main form to a report? or do i have to do the same calculations on the report itself?
I have a form which works good enough. In this form, there is a text box that counts and calculates records from a subform. The name of this text box is "text1" ...
