Hi,
I have 3 nested forms and want to calculate a total on the first
subform (as the form loads)by adding 2 fields from that form
[deposit]+[rental] to a field on the second subform.
Second subform is [transactional subform] and control is Sumpd.
I use this
=[transactiontbl subform].Form!Sumpd+[deppd]+[rentpd]
which works well as long as the transactiontbl subform has records in
it. Problem is this subform will often be empty. I then get error as a
result in my calculated control. Have tried using Iif statements eg
=IIf(Me![transactiontbl
subform].Form.RecordCou nt=0,[deppd]+[rentpd],[transactiontbl
subform].Form!Sumpd+[deppd]+[rentpd])
but as a newbie am surely writing something wrong!
All forms are nested with master/child fields linked. Table
relationships also look OK.
Any help much appreciated.

Try - Nz([transactiontbl subform].Form!Sumpd) + Nz(deppd) + Nz(rentpd)
I'm not sure it will work, but give it a go. Nz is used to convert Nulls to
Zeros.
Incidentally you don't need square brackets [] round field name or table
names PROVIDING there are no spaces in them. Makes expressions a little
simpler, but suggest you never use spaces in field name e.g. use
TransactionTblS ubform

Hi,
As you all know when an ASP.NET web form is created that will include
web controls and such, it contains a
FORM that that identifies the web form and its containing controls.
Well, I have a web form who has several other (user & custom) controls,
these are enclosed within the standard
FORM tag. Additionally *some* of these user controls are actually forms as
well. This results into nested Forms.

I've got a main form (frmMain) with 5 subforms on it. All subforms are
