Try this version
=SUMPRODUCT(SUMIFS(B3:B10,A3:A10,C3:C6))
because the criteria range is four cells the SUMIFS function will return an "array" of four values - SUMPRODUCT is used to sum those four values
You can also use SUM but the formula needs to be "array entered", i.e.
=SUM(SUMIFS(B3:B10,A3:A10,C3:C6))
confirm with CTRL+SHIFT+ENTER
