I wanted to do something similar, and it does not sum it up.
Can you please help.
Thanks in advance

=SUMPRODUCT( --(C1:C10 1), --(C1:C10 < 2), D1:D10 )
C D
1.1 3
1.2 2
1.3 1
2.2 3
2.1 1

Nope to =sumif()

But you could use:

=sumproduct(--(a1:a100<date(2006,12,1)),--(b1:b100="silic"),
--(c1:c100="toronto"),(d1:d100))

Adjust the ranges to match--but you can't use whole columns (except in xl2007).

=sumproduct() likes to work with numbers. The -- stuff changes trues and falses
to 1's and 0's.

Bob Phillips explains =sumproduct() in much more detail he

And J.E. McGimpsey has some notes at:
