Hello,
I am trying to sum but to a closed external file.
I know that I can use SUM(IF()) Array formula.
I am wondering how do I use SUM(IF()) Array Formula with AND multiple criteria?
In the past, the formula below works
But the above formula is only having 1 criteria.Please Login or Register to view this content.
What if I want multiple criteria and that all criteria needs to meet.
Thanks!
