B6:b45 includes a list of ID numbers. Some of the ID numbers will be repeats. I need a formula that will count the number of different IDs.
Thanks.

Make sure there is no empy cells in that range.
=SUM(1/COUNTIF(B6:B35,B6:B35))
after you put that in the formula box, press control, shift and enter
Hope that helps
Google is your best friend!
Try...
=SUMPRODUCT((B6:B45<>"")/COUNTIF(B6:B45,B6:B45&""))
Hope this helps!
