Hi

if your data is only numeric and doesn't contain blanks you can use the
following formula from Chip Pearson's web site
=SUM(N(FREQUENCY(A5:A7,A5:A7)>0))

where A5:A7 is the range of your values.

If you will be dealing with text or your data could have blanks in it -
check out Chip's page on duplicates at:
http://www.cpearson.com/excel/duplicat.htm
- about half way down you'll find an article on counting unique entries in a
range.

Cheers

The formula below assumes your data is in the range A1:A3. Enter this
formula as an array (select the range A1:A3, put the formula in the formula
bar, and press CTRL - SHIFT - ENTER at the same time):

=SUM(IF(FREQUENCY(A1:A3,A1:A3)>0,1))

This Microsoft Knowledgebse article explains things a little more:

If the column might contain blank cells, try this:

=SUMPRODUCT((A1:A30<>"")/COUNTIF(A1:A30,A1:A30&""))
