Hi

Sumif won't work in that way

Try
=SUMPRODUCT((Jan!$BY$3:$DL$3=Projects!$C6)*Jan!$BZ $263:$BZ$266)

But wahat do you expect your result to be?
Supposing your first set of values are 5, 10, 15
Your comparison value of the other sheet is 10
Your column of values is 20,30,40

The above formula would give a result of 90
If however, the first set of numbers were 10, 10, 10 then the result
would be 270

this formula seems to work but only returns the number from BZ263 not the
sum of the whole range.

As you see it does access 2 sheets and the first criteria is across columns
the 2nd down a list of rows.

Suggests???
