The syntax of COUNTIF is COUNTIF(range-A, criteria, range-B)
The syntax of SUMPRODUCT is SUMPRODUCT ( array-1, array-2, ...)
You are making arrays so SP works, Countif does not
any help?

I am receiving "the formula you typed contains an error" when I try to
execute the following formulas. Any ideas why these don't work?

=COUNTIF((--(J2:J2000=E8),--(K2:K2000=E9)),M2:M2000)
=MAX(IF((--(J2:J2000=E8),--(K2:K2000=E9)),M2:M2000)))

when this one does...

=SUMPRODUCT(--(J2:J2000=E8),--(K2:K2000=E9),M2:M2000)
