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))
and it spit out the correct answer. Now the same spreadsheet on a Mac running Excel 2004 for Mac gives that a #VALUE!
error. Any thoughts on why?

This is exactly a question for Joel. – UnkwnTech Jun 20 '09 at 23:23

He might say he didn't work on the Mac port of Excel :p – shahkalpesh Jun 21 '09 at 00:04

What does "same spreadsheet on a Mac" mean? Did you copy it or did you type the formulas in again? – John Machin Jun 21 '09 at 07:29

I realize that the post was mede a long time ago, but i recently and regularly have the same problem - and I always seem to forget the solution: Select the cell or range of cells that contains the array formula, press CONTROL+U to edit the formula, and then press ⌘+RETURN.
You need to enter it as array (matrix) formula. After typing the formula don't hit enter but hit either
CMD+SHIFT+ENTER or CTRL+SHIFT+ENTER
Where CMD is the apple key. I'm not sure what the keycombination is on mac. But you can check in the help file. Entering array formula

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.

As far as I know, the separator is locale-dependent and is used only for formula entry and display; it's not actually stored in the compiled-into-RPN formula saved in the file. In any case it's easy to determine: type in =SUM(1,2) in one cell and =SUM(1;3) in another; one will produce 3 and the other will produce an error dialogue box -- you won't get as far as #VALUE! because the formula is syntactically incorrect. – John Machin Jun 21 '09 at 07:40
I'm not sure if this is mac-specific. I have always used
=COUNTA(G$19:G$1034)
for this purpose.
