Sumproduct Array Formula

The attached sheet has test data for what I am trying to accomplish. Range F4:AE4 has one set of criteria. That criteria should match AI724:AI750. The Date range is C5:C140. The criteria for that range is AK4:DF4 is one week increments. The values to sum are in range F5:AH140. So there are multiple criteria for the SumProduct. It all seems simple enough, but maybe it is weekend mind block. And help here would be greatly appreciated.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. 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.

Use this formula in AK724, copy and paste as formula down and across.
It is not an array formula.
=SUMPRODUCT(($C$5:$C$140<=AK$4)*($C$5:$C$140>AJ$4)*INDEX($F$5:$AH$140,,MATCH($AI724,$F$4:$AH$4,0)))
