Try this array formula** :

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

Hello,

I'm trying to count unique numbers in a resulting list after filtering. I
have already learned how to count unique number in an unfiltered list
using:

=SUM(IF(FREQUENCY($A$12:$A40,$A$12:$A40)0,1))

but now I need to know how many unique numbers remain after I filter for
another column. Help!
