I would like to use named ranegs, if possible, to replace the function
SUMPRODUCT with the abbreviated nam "SP." I created the named range SP and
called it sumproduct, but I have not been able to make it work.

this function
=SP&"(--($H$4:$H$21=J5),--($F$4:)$F$21))"
gives me as a result
sumproduct(--($H$4:$H$21=J5),--($F$4:)$F$21))
but does niot give me the result of that formula.

any help would be greatly appreciated.
