I am using Excel 2007. I would consider my level of Excel expertise to be between intermediate to advanced.

However, I just came across the strangest problem with my Excel which I can't resolve.

My Excel 2007 functions are completely unable up accept anything more than a single argument.

=max(3) is fine
=max(3,4) generates an Excel error message

=sum(4) is fine
=sum(4,9) generates an Excel error message

Is anyone able to help out?

This is the strangest of strange error which I'd ever come across...I tried Windows Updates, reboot, restart, even reinstallation... Nothing works.


Help....tx
