I need to count the number of items that have the designation of "R" (Column
A) and that also have a designation of "1" (Column B). I have tried several
different formulas, but always get the return value of "0" (Zero).

Formulas tried:
=sumproduct(('Test Map'!G4:G126="R")*('Test Map'!T4:T126="1"))
={SUMIF(('Test Map'!G4:G126= "R")*('Test Map'!T4:T126= "1"))}
=SUMPRODUCT(('Test Map'!$G$4:$G$126="R")*('Test Map'!$T$4:$T$126="1"))

Any ideas?
