I looked at the postings for Sum if and Sum product, but can't get it to do
what I need. I want to count the total hours for Pam if she is listed for a
shift (G9:M16). The hours of the shift are in F9:F16 (see below)

I've tried =SUMPRODUCT((G9:M16="Pam"),F9:F16) & received a value error.
=SUMIF(G9:M17,"Pam",F9:F16) only results in 7.5, counting her first occurence.
