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

It might be settings that control the separator character. That "," is the separator on one machine and something else, for example ";" is the separator character on the other.
