Function to count unique items in list
 

I am using Office 2003 on Windows XP.

Is there a built-in function in MS-Excel that gives you a count of the
unique items in a list?

If so, what is it called?

If not, how can I create a user defined function to do this?

Thanks much in advance.

Try this:

For a list in A1:A10

=SUMPRODUCT((A1:A10<"")/COUNTIF(A1:A10,A1:A10&""))

Adjust range references to suit your situation.

Does that help?
