JOIN COLLECT with multiple criteria including star - need help!

Trying to do a JOIN COLLECT to collect multiple data points from one column (candidate full name) when there is a match to the current row (faculty@row) and the row is starred (cohort@row). Formula below, getting #INCORRECT ARGUMENT SET error. When I test only the Faculty@row range/criteria, the formula works. When I test the starred column range/criteria, it doesn't.

=JOIN(COLLECT([Candidate Full Name]:[Candidate Full Name], Cohort@row, 1, Faculty:Faculty, Faculty@row), ", ")

Any suggestions?
