I have the following calculation in an Excel 2007 worksheet and I need to tweak it slightly if anyone can help?
=IF(SUM(A18)>0,SUM(A18*E18),"")
The above Calc multiplies cell A18 by Cell E18 and displays the result in cell F18 but only if cell A18 has a value greater than 0 and it works fine, however, I want to change it slightly to stop it placing a zero in cell F18 once a value is put into cell A18
I want the calc above to work only if the value in both A18 and E18 is greater than zero.
