Return null (blank) instead of zero

I have written an expression using the IIF function. It evaluates two number
fields and performs a calculation. I would like to display null (blank) if
the expression returns a value of zero. Is this possible?

If you want it to display blank then you can use the control's format to set
that.

Set the format as follows
#;-#;"",""

If you want it to BE null then you need to do the calculation and test the
result and then either return Null or the value of the calculation
So if your original IIF is
IIF(AB,A*B,A)
Then it now becomes
IIF( IIF(AB,A*B,A)=0 ,Null, IIF(AB,A*B,A))

Adding the variable Null was the solution I needed.

Thanks for your help, Dawn
