In my Form/Subform relationship the subform contains a checkbox I would like that each time the checkbox is either set to true or false the running total on the the main form would requery.  It seems to only update after a second action has been performed.  When I check one box my total says $0.00 after I make a second it reflects the total amount from the first selection.

Here is what Im using:


Dim RunningTotal As String
If DCount("*", "[qryRunTotal]") > 0 Then
    RunningTotal = DLookup("[RunTotal]", "[qryRunTotal]")
    Forms!frmToBeAdjusted!Text57 = RunningTotal
Else
    RunningTotal = "$0.00"
    Forms!frmToBeAdjusted!Text57 = RunningTotal
End If

Hi,

You need to place the calculations in the AfterUpdate event of the checkbox.

Best regards,

Bill

Hi again,

In looking at your code if the query relies on data that may nave been updated then you need to save the record.  This is in addition to putting the code in the AfterUpdate event of the checkbox.

Add:

DoCmd.RunCommand accmdSaveRecerd

as the first line in the AfterUpdate event then run your process to get the subtotal.

Regards,

Bill

Hi,

In general if you are running a query that is using data on the form you need to push that data bak to the db so the query can find the current values.  You can put a running total on the form footer and get the result you are seeking without code if trhe values to be summed up are on the form.

Set the recordsource for Forms!frmToBeAdjusted!Text57

=Sum([FieldName])

That will always display the total.
