Eric,
I didn't read your question correctly. I can't determine how you got the 4, 3, 4 results
you want in the example. It appears to me that Tom, Sam, Phil and Pete have entries in the
Feb column, so the result should be 4, not 3.
Take a look at Chip Pearson's page http://www.cpearson.com/excel/duplicat.htm. There is
stuff for duplicates, including counting uniques. Maybe you can get where you need to be
starting there.

top-posted, the thread gets messy. When in Rome.

Thanks Earl. I'll check it out.
Yeah trying to represent data is a mess here. Here where I want to get:
There were 4 unique people billing in Jan - Tom, Sam, Phil, Pete
There were 3 unique people billing in Feb - Sam, Phil, Pete
There were 4 unique people billing in Mar - Tom, Sam, Phil, Pete
Thanks
JAN FEB MAR
A Tom .25 .5
A Sam .25 .4 .5
A Phil .25 .5 .5
A Pete .5 .5 .75
B Sam .1 .4 .5
B Tom .4
