Hi,
I have a question here, appreciate any help.

Prod ID Jan Feb Mar....
Prod A 10 5 3
Prod B 3 - -
Prod A 4 7 1
Prod C 5 2 7

In Cell A8 = Prod A

At cell B7, it is a data validation(drop-down list) for Jan~Dec
In B8 cell, I need a formula to calculate When Prod ID = Prod A and when
month selected is Mar, the sum, ie. result is 4.
In C8 cell, I need a formula to calculate When Prod ID = Prod A and when
month selected is Mar, the count if value is 0, ie. result is 2

I know I may have to use sumproduct, some lookup in order to get the result.
But just couldnt get them into the correct manner.
Thanks in advance for your help.
Merry Xmas!
regards,
