Hello Excel(lent) users,

I want to know the following
A (Priority) B (numbers) C (week)
--------- -------------- -------------
1 12 6
2 11 6
3 14 5
1 11 4
1 11 6

How much numbers have been closed in week 6 with priority 1?
In the above example it is 12+11 =23.

How can I get this information, by using sumproduct?

Please help me !

Thanks!
