Hi there

I am developing a skookum s/s where I am returning values based on various
criteria and am using sumproduct. The issue seems to be with the format of a
cell.

Here is one of my calculations.
=SUMPRODUCT((Actuals!$A$2:$A$7500<"Q4")*(Actuals!$ D$2:$D$7500="40TKB")*(Actuals!$B$2:$B$7500=50)*Act uals!$J$2:$J$7500)

It is returning zero. However, if I put the 50 in quotes, it will return
the correct value. My issue tho is that some of the calculations don't need
quotes and some do. Eg, if I put "6531" in the following equation it will
return 0.
=SUMPRODUCT((Actuals!$A$2:$A$7500<"Q3")*(Actuals!$ D$2:$D$7500="40TKB")*(Actuals!$F$2:$F$7500=6531)*A ctuals!$J$2:$J$7500)

I have not formatted the cells at all but they are exported from a home
grown system. I've played around with changing the format of the columns to
Number and general with no change. Any help would be great as I do not trust
my formulas as yet
