I'm not sure if this will work, but try it

=SUMPRODUCT(--(OFFSET(Sheet1!$A15,0,Sheet1!$Q$1,146,1)=$A$15),(O FFSET(Sheet1!$A15,0,Sheet1!$Q$1,146,1)))

I am using the following:

=VLOOKUP($A15,$A$81:$AB$124,Q$1,FALSE)+VLOOKUP($A1 5,$A$126:$AB$160,Q$1,FALSE)

Where $A15 may not exist in either of the arrays or only in one of the two.

How do I allow for this so I get a value rather than the #N/A?

Thanks in advance
