You don't explain what you mean by *math calculation.* If the *math
calculation* was say (A5+D5)/F5 then the IF() formula could be something
like:
=IF(COUNT(A5,D5,F5)=3,(A5+D5)/F5,"")
This will show the result of the calculation only if all three cells have
values.
Post back with more information so that we can help you.
