Subform total on Main form

Subform total on Main form

Subform total on Main form

How can I total up the Sum of a subform on the Main form? The fields that is linked is the PONo. The subform is in continous view.

Thank You

RE: Subform total on Main form

Put a textbox on your subform in the footer.
Call it something like Total and put the =Sum([Fieldname]) in it's control source.
Then put a unbound text box on the main form.
Its control source will be the textbox on the subform.
After you have the formula working make the textbox on the subform invisible.

RE: Subform total on Main form

I do it a fair bit in A2K

The hypothetical situation is: On the sub-form each line has an amount & you want to show the sum of all line amounts on the main form.

1) On your sub-form create a sum control in the sub-form footer, like:

Name:    SubFormTotal
Control Source: = Sum([Amount])
Visible:    False

2) On the main form... create a control to reference the totaling control of the subform... err, that's the one you just created. Sooooooo

Name:    ShowTotalFromSubform
Control Source: =[>>Insert Sub-Form Name<<].Form![SubFormTotal]

As long as you reference the full name of the sub-form's control you can perform any number of calulations on that "Sum()" from the sub-form. & it works for reports too.

i do something like... where i lifted the code

Name: PAFSubReport

Sub-report's Control:
Name: DocTot
Control Source: =Sum([Amount])

Main report's control: 'shows one month of salary
Control Source: =IIf([PAFLayout]="A",[PAFSubReport].Report![DocTot]/12)

hope this helps
