Dear Experts,

Wondering if you all could help me with this expression:
The following expression is in the control source of txtPercentPos:
=Format((Val([txtPosCnt])/Val([txtPosCnt])+Val([txtNegCnt]))/100,"#%")

Open in new window


but when I display the continuous form I get:

How can I prevent the error from happening if there are no values in the txtPosCnt or txtNegCnt textboxes?

Thanks!

Does this work?

=Format((Val(Nz([txtPosCnt]))/Val(Nz([txtPosCnt]))+Val(Nz([txtNegCnt])))/100,"#%")

Open in new window

Try

=Format(IIf(Nz([txtPosCnt], 0) = 0, "", (Nz([txtPosCnt], 0) / [txtPosCnt] + [txtNegCnt])) / 100, "#%")

Hope I have the parens in the right place ...

Joe,

This works if txtNegCnt is blank but errors if txtPosCnt is blank as well. Can you assist with check if both fields are blank?

Cool.  Mainly, you have to prevent Divide By Zero ....and ... Null propagation - hence the Nz() to convert Null to Zero.

Sorry ... I went to bed shortly after that post.
