Sum with multiple criteria - formula help

[PivotMeThis]

My report contains data for employees working on projects for each pay period for the past several years. I need to sum the labor hours (column M) for each employee (column H) on each project (column I) for each year (column S).

I need the total on the first row.

I've used countif/sumif in the past but there is just too many items for me to figure this out.

example (I use this formula in a different report): if(countif(k$2:k2,k2)>1,"",sumif(k:k,k2,m:m)) I thought it might be a starting point but I'm totally lost.

I really appreciate your help.
Thanks

Can you provide some sample data and what the expected outcome is?

Will this do? Or do I need to do something else?
