[AccessD] Referencing Fields in Sub-Reports

Hi Mark

Your problem is that the control doesn't even "exist" when there are no
records.
Thus, you may need something like this (one line):

  IIf(Report!rptMain!<sub1>.Report.RecordsetClone.RecordCount = 0, 0,
Report!rptMain!<sub1>.Report!txtTextbox) +
  IIf(Report!rptMain!<sub2>.Report.RecordsetClone.RecordCount = 0, 0,
Report!rptMain!<sub2>.Report!txtTextbox)

Thanks Andy and Gustav.
Using the syntax "rptSub1.Report.txtTextbox +
rptSub2.Report.txtTextbox"
seems to work.  Although, this only totals the values when there are
legitimate values in each textbox.  If one of the boxes contains a
null
value, the report is showing "#Error" in the field.
I'm thinking that I want to force the subform's textbox value to 0 if
it's null, but this doesn't seem to be working.  I tried using
"=IIf(IsNull([TextboxValue]),0,[TextboxValue])", but this still
displays
a null value.

Does this make sense?
Thanks,

Hi Mark and Andy

There used to be a document on the DBA site which listed how to
reference parent and child forms and reports.
Where did it go??

But it should go like this:

  Report!rptMain!<NameOfSubreportControl1>.Report!txtTextbox +
  Report!rptMain!<NameOfSubreportControl2>.Report!txtTextbox

I think the ref within rptMain would just be to

Me.subrpt1.report!txt1

Remembering that subrpt1 is the subform control within rptMain not the
report name.
