Formula doesn't work correctly

=IF(A2="","",SUM(C$2:C$20000))/12

The problem I have is cell A2 will not have anything there, but I get a #VALUE! result. If A2 actually has data, then it shows the result. Can someone tell me how to make my cell that this formula is located in return back blank if A2 is blank. Thanks,

Do the /12 on the result of the SUM, not on the result of the IF.

When your IF condition is FALSE, then IF returns ""
""/12 = #Value!

Try
=IF(A2="","",SUM(C$2:C$20000)/12)

You're a Genius!!! Thanks a ton

You're welcome.
