Offset your arrays in a SUMIF function like so:

=SUMIF(AH4:AH127,"T1",AG3:AG126)

I'm having trouble with one of my files in excel. Basically I want it to be
so that if a cell in column AH4:AH127 has T1 in it, then I want the sum of
the cells in column AG4:AH127 that are one row above where it has the T1 in
AH. for example if AH12 and AH55 have T1 in them, then I want the sum of
AG11 and AG 54.

I can't move the values from AG to be in the same row as the T1 in AH
because there is already other data there.

Any help??
