Excel formulas giving #VALUE! error when ported to Mac

Question

I want to be able to sum up the number of cells in a range that have a non-null value in them. On a PC running XP and Excel I entered =SUM(IF(G$19:G$1034=\"\",0,1))

Answer 1

I'm not sure if this is mac-specific. I have always used

=COUNTA(G$19:G$1034)

for this purpose.
