Simple problem with addition on a form

Hello,

I have 10 optional numerical fields on a form.
When I try to sum them in the control source of another input box, or
even using VB, I only get a working total if all 10 fields contain a
number.

How do I tell access to ignore fields with no number entered and also
fields containing "#Error?" so that I always get a total in the total
box?

Thanks

Look up the Nz function in VBA Help.
=Nz([FieldA]) + Nz([FieldB])+Nz([FieldC]) + etc.....

You probably need to use NZ().
=NZ([fld1],0)+([fld2],0)+([fld3],0)...

I wouldn't know. Most people would fix the #Error.

Ha ha the error was actually caused by the same problem somewhere
else! I used an IIf (which I just discovered!) to fix the error and
then the Nz function to fix the totals problem. Thanks a lot for the
help guys!
