Biff, I think you have missed the point which OP is raising.

No, that was already answered. I was making a suggestion based on the
generic count of uniques formula TM posted with regards to "big" ranges.

i have about 7000 rows

Array entered** :

=SUM(IF(FREQUENCY(IF(A1:A7000<"",MATCH(A1:A7000,A 1:A7000,0)),ROW(A1:A7000)-ROW(A1)+1),1))

** 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.

The array formula is significantly more efficient on a range that size.

AVG calc time on 7000 rows:

SUMPRODUCT = 2.88 secs
FREQUENCY = 0.09 secs
