Hi

Under what scenarios might a SUMIF function in a worksheet no longer work?
I created a spreadsheet for a client with one of the process steps involving
a SUMIF function. It has been working fine for over a year (with a monthly
reporting process) but all of a sudden this month it is not yielding any
result at all.

The result is a "0" but I can eyeball the data and clearly see that there
are values that should be summed...

....If anyone has any ideas I would be most grateful.

Thanks!
