Calculated Field On Form

Feb 21, 2008

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?

Thanks!

Calculated Field On A Form Problem

Jul 4, 2006

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.

Help is much appreciated.

Calculated Field From Form To Table

Sep 18, 2006

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.

Possible To Filter A Form Based On A Calculated Field...?

Apr 12, 2006

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???

Forms :: Calculated Field On Main Form

May 31, 2013

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.

code

Private Sub TxtSoldQty_AfterUpdate()
On Error GoTo HandleError
Me.ExtTaxIn = (Me.TxtSoldQty * Me.TaxIn)
Me.ExtPrice = (Me.TxtSoldQty * Me.Price)
Me.InvSold = (Me.TxtSoldQty * Me.UnitOfSale)
Forms!frmShiftMain!TxtShiftTotal = Forms!frmShiftMain!TxtRunningTotal
Me.txtExtTaxIn.Requery

[code]...

This sort of works but the [ShiftTotal] on the main form is always one table row behind. I think this is because of the order the event fires.

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)?

Calculated Field Pull Total From Another Report Or Form

Dec 16, 2004

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.

Help with the formula? please?

I Need To Update Data In A Table With Information From A Calculated Field In A Form

Oct 12, 2006

I'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.

Forms :: How To Update Main Form From Calculated Field In Subform

Aug 21, 2013

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.

Forms :: Calculated Field In A Form - Populate Series Of Number

Apr 24, 2013

I have created a form that is based on a table.

The fields in the form are currently pull downs or manual enrty fields (all based on the columns of the table... "Bound" I think you call it).

I also have fields that I manually brought into my form as text boxes that I am using to populate a series of numbers. I have named them P1, P2, P3 etc. They are unbound fields.

I have a field that I am totalling the unbound fields. It is a column in my table. At one point the control source name was the table coulmn name.

I have changed the control source to read =[p1]+[p2]+[p3]+ etc.

The total does show up in the field on my form

HOWEVER.... When I save the data the total number does not get brought into the table. All of the other fields do.

Basing A Calculated Field On Another Calculated Field

Apr 12, 2006

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.

I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.

Does anyone know how to correct this? Thanks in advance.

:confused:

Calculated String Input Field In An Input Form.

Jan 30, 2005

Hello,

I need to create a field in an input form that is simply the concatenation of two other text fields. I have tried all sorts of things, but when I look at the data in the table that field.

I have a field called ID that I want to be created like this:

=Format([UniqueID],"00000") & "-" & [Mosque]

This works well in my output fields, but does not work the same way on the input form. It needs to be based on the currently input values from the current record. Anyone have any ideas?

Thanks in advance,
--Robert

Queries :: Calculated Field To Display Value Of One Field Based On Another

Jul 23, 2015

I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:

10Jul15: Sales
and then adding Criteria like:
EndDate = #10/07/2015#
It doesnt work.

Calculated Field

Feb 9, 2006

Hi,
I have a calculated field in a query that concatinates an order number prefix and the part number to give the order number:
OrderNum: [OrderPrefix] & [PartNum]

There are 2 tables:
tblPartsList
PartNum
PartDesc

tblPartsListCategories
OrderPrefix
OrderNumCategory

This works fine except for one of the categories. For the third category there are no entries in the tblPartsList - because they are miscellaneous.

How do I change the calculation so that it works as above where there are corresponding Part numbers in tblPartsList and otherwise gives me the order number and any 2 digits e.g. something like [OrderPrefix]*

Having been trying to do this for ages but having trouble with syntax.
