=IF(Sheet1!A1-Sheet1!B1=0,"",Sheet1!A1-Sheet1!B1)

Or if you want to see a zero when the difference evaluates to a real zero

=IF(AND(Sheet1!A1="",(Sheet1!B1="")),"",Sheet1!A1-Sheet1!B1)

Hi,

I have an excel sheet with data in columns A & B on TAB 1 and I am trying to
have the DIFFERENCE of TAB 1-Cell A1 & B1 in TAB 2-Cell A1.

My Cells A1 & B1 of TAB1 are empty (have nothing in them) and when I apply
the formula I get "0" as result in Cell A1-TAB 2.

Is there a way to NOT get '0' in the result cell with the formula still
being in there even when your data cells are empty?

Please help.

Thanks
