Not sure what you're wanting to do but this is a more efficient way to write
that formula:

=SUMIF('Aug 08'!$M$10:$M$438,Tina!A7,'Aug 08'!$N$10:$N$438)

{=SUM(('Aug 08'!$M$10:$M$438=Tina!A7)*('Aug 08'!$N$10:$N$438))}

I have the above formula in (Worksheet Tina) and I want to look up the
information in Column A of that worksheet to match information in
(Worksheet
Aug 08) Column M and if the information matches to return the value in
Column
N. I am not sure what I have done incorrectly can you please assist me.
