How do I return a unique count where conditions exist? This works until I
try to add conditions. HELP!!!

This works:
=SUM(IF(FREQUENCY(MATCH(A4:A9216,A4:A9216,0)|MATCH (A4:A9216,A4:A9216,0))0,1))

When I add conditions it doesn't:
(IF(B4:B9216,"HO")+IF(C4:C9216,"P")SUM(IF(FREQUENC Y(MATCH(A4:A9216,A4:A9216,0)|MATCH(A4:A9216,A4:A92 16,0))0,1)))
