Sum if function

[Lostlobos]

I would love some help with the following. I am trying to get the Total sum of column C when Column A equals a particular value and Column B equals another value. I think the answer lies in the Sum if function (in conjuction with something else), but I am having a difficult time figuring out. Any suggestions?

try SUMIFS instead

=SUMIFS(C:C,A:A,"value1",B:B,"value2")
