Sum with dynamic range

Hi, I need some help with a formula I can't seem to figure out. I have a dataset of sales by weeknumber and year. When I select the starting week+year and end week+year (from a dropdown menu), I want the sum to automatically adjust.
I attached an example sheet. In yellow is what should be the outcome of the sum.
Many thanks for your help!

One way:

=SUM(INDEX(C$2:C$500,MATCH(1,INDEX(((E$2:E$500=H2)*(D$2:D$500=G2)),0),0)):INDEX(C$2:C$500,MATCH(1,INDEX(((E$2:E$500=H5)*(D$2:D$500=G5)),0),0)))

You're welcome.

Yep. Shift to SUMPRODUCT, as combineing years and week numbers is messy with SUMIFS:

=SUMPRODUCT(($A$2:$A$500=$K$3)*($B$2:$B$500=$J$3)*(($E$2:$E$500+$D$2:$D$500/100>=$H$2+$G$2/100)*(($E$2:$E$500+$D$2:$D$500/100<=$H$5+$G$5/100)*$C$2:$C$500)))

Really ?
It is not only shorter but quicker

=SUMIFS(C:C,E:E,">="&H2,E:E,"<="&H5,A:A,K3,B:B,J3)-SUMIFS(C:C,D:D,"<"&G2,E:E,H2,A:A,K3,B:B,J3)-SUMIFS(C:C,D:D,">"&G5,E:E,H5,A:A,K3,B:B,J3) 26,99219

Whatever...
