I'd go into windows control panel, regional settings and make sure that the list
character is a comma.

When entering a function like "countif", the tool tip shows a square where
the comma should be in the tool tip and I can not get past the range portion
of the function. I have re-installed excel 2003 and still have the same
problem. Is there some system setting that has changed? I can not use excel
the way it is.
