MATCH returns 1 if it finds a match in the first cell of the array, so
if we used

...OFFSET(OFA!$DM4, 1...

it would start with DM5.

An alternative would be:

=SUM(OFFSET(OFA!$DM4,MATCH(A2,OFA!$D$4:$D$6000,FAL SE) - 1,,,4))

I don't understand though why the you are replacing the DM4 and DM3 though.
Would have thought DM4 would have stayed DM4. If you have time, can you
explain how that works? I need to understand OFFSET better... thanks very
much for your help. SteveC

One way:

=SUM(OFFSET(OFA!$DM3,MATCH(A2,OFA!$D$4:$D$6000,FAL SE),,,4))
