Subform Default Value

[Guest]

I have created a sum calculation in a subform that is then referenced in the
form. Is there a way to have the calculation return a 0 value if no records
are present in the subform?
I have changed all the default values to 0 in the properties and have tried
the formula =Sum(Nz([ActualAmount], 0)) without success.
If I enter a record in the subform with value 0 everthing works, but I don't
want to have to do that for every record.
Thanks in advance for your suggestions!

Set the main form control's ControlSource to:

=IIf(IsNull(YourSubformSummaryField),0,YourSubformSummaryField)

This worked PERFECTLY for one subform, but won't work for the other. When I
run the main form, a 0 and the correct calculation flashes and then goes
away. There is no error, just an empty field. Does this make sense at all?

Thanks so much for your help!
