Excel Formula need help

[coan.jim]

I am trying to get a count of one column based on criteria in another
column

Column B always equals either 'true' or 'false'. I need to find a
count of 'true". (True being the test was taken)

so If A:A= 'test#3', then count # of 'trues' (in column B:B), related
to the same test name in A:A

Please help and thanks

=SUMPRODUCT(--(A2:A200="test3"),--(B2:b200=TRUE))

SUMPRODUCT won't work with whole columns.
