Did you enter the formula as an array?

The IF portion of the formula makes it an array.

Enter it using the key combination of CTRL,SHIFT,ENTER (not just ENTER).

Another Excel user states that this equation works on his computer

=SUMPRODUCT(IF(C10:C21<1099.41-F10:F21,C10:C21,1099.41-F10:F21),M10:M21)

However, when I formula audit - it gives me a value error on the first
c10:c20.

I know that all my values are good. If I remove the "IF" I can get an
answer - again just confirming that it is not a problem with the data.
I'm
using v. 2003

Any ideas
