I've been struggling with this for a while...

The following formula works, and returns the needed answer; however, i would
like to link the "1123" to cell G5, so I can copy down the formula and have
it calculate for the different building codes. My problem is that when I
link the "1123" to the cell, it returns a -0- everytime. In the second
array, I have referenced cell Q$1, which works fine.

I have tried formating G5 as general, text, number. I have recalculated the
spreadsheet. I have named the cell, then tried to reference that.

I am fresh out of ideas.

=SUMPRODUCT(--('3Q06 Occupancy.xls'!Building_code_Column="1123"),--('[3Q06
Occupancy.xls]Occupancy'!$G$4:$G$159=Q$1)*('3Q06 Occupancy.xls'!HC_Column))

Help Please??
