Count but ignore duplicate data
Hi,
One way =SUMPRODUCT((A2:A10<"")/COUNTIF(A2:A10,A2:A10&"")) Note that Bernd P has done an analysis of different methods of doing this dependent on dataset size. look here. http://www.sulprobil.com/html/count_unique.html -- Mike When competing hypotheses are otherwise equal, adopt the hypothesis that introduces the fewest assumptions while still sufficiently answering the question.

Count but ignore duplicate data
Glad to help but don't forget to check out the link I gave you because the
sumproduct method becomes very slow for larger datasets and the website has other better methods -- Mike When competing hypotheses are otherwise equal, adopt the hypothesis that introduces the fewest assumptions while still sufficiently answering the question.
