I have 2 functions that are calculating my data correctly, except now I need
to consider the autofilter. I figure using subtotal is the way to go if I
want to disregard filtered out rows. Also, I plan on moving my data to
another sheet, so it will need to reference the current sheet, which is
AAT_Raw_Data. Finally, the # of rows of data will vary, but I don't think it
will ever be over 10,000. I'm using Excel 2003, so I think there's an issue
with using something like "A:A" in my formulas.

Can someone help me change these to add in a subtotal and take into account
the other things I mentioned?

FORMULA 1: SUMIF(A:A,I5601,C:C)

FORMUA 2: SUMPRODUCT(--($A$1:$A$9995=I5601),--(E$1:E$9995=1),($D$1:$D$9995))

Much Thanks!
