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))
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
I'm not sure if this is mac-specific. I have always used
=COUNTA(G$19:G$1034)
for this purpose.
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.
