I am using the following formula as part of my data source for a chart and it
works perfectly. It sums column D, rows 2 through 20K where the value in
column A, rows 2 through 20K = cell G2 and where the value in column E, rows
2 through 20K = 1. The SUBTOTAL allows for any filtering on my source tab
(AAT_Raw_Data) to dynamically get factored in.

=SUMPRODUCT(SUBTOTAL(9,OFFSET(AAT_Raw_Data!$D$2:AA T_Raw_Data!$D$20000,ROW(AAT_Raw_Data!$D$2:AAT_Raw_ Data!$D$20000)-ROW(AAT_Raw_Data!$D$2),0,1)),--(AAT_Raw_Data!$A$2:AAT_Raw_Data!$A$20000=G2),--(AAT_Raw_Data!$E$2:AAT_Raw_Data!$E$20000=1))

I need to alter this a bit. I need a count of cells in column B, rows 2
through 20K where the value in column A, rows 2 through 20K = cell G2 and
where the value in column D, rows 2 through 20K = 180. I still need to
factor in any filtering that might happen on tab (AAT_Raw_Data).

It seems the only real difference is that I need a count instead of a sum. A
couple of the column references are changing, but that's not what I'm stuck
on.

Can someone help me with this?
