This is my original equation: =([Total Maintain Exercise]/[Total
Completing 1 mo Follow-up])*100

When the denomimator is zero I am unable to calculate the percentage.

I tried changing my equation to this format:
=IIf([denominator_field] = 0, 0, [numerator_field]/
[denominator_field])

I also tried:

IF(B=0,0,A/B) will give you an answer of 0 if the
denominator is zero or IF(B=0,"",A/B) will give you a blank in the
same
situation.

Any suggestions...I am desperate as I was hoping this would be an EASY
fix!

Thanks!,

John

Why not use/create a function in a code module?
Function DivideIt(a,b) As Variant
If b <> 0 then DivideIt = a/b
End Function
and insert as the control source
=DivideIt([FieldValue],[FieldValue]}
