I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Thank you.  Rgonzo's accounted for the years which is what I was after.  August 2016 and August 2017 were the same answer under Professor's.  I might have not made that so clear though.
Professor JMicrosoft Excel ExpertCommented:
glad Rgonzo's solution worked for you. i did not notice at first glace your data had multiple years, so i posted a modified formula which is =SUMPRODUCT((MONTH($B$3:$KV$3)=MONTH(B$1))*((YEAR($B$3:$KV$3)=YEAR(B$1))*($B$4:$KV$4))) which works too.
