Hi Joe,

I have a list of Session names in column A (could be just 1 or more then
25). I would like a formula that looks a column A and if A1 is the same
as A2 then put the number 1 in column B. This numbering would continue
until the name in column A does not match the name below, when this
occurs the numbering would start over at 1.

in B1 try:
=COUNTIF($A$1:A1,A1)

Claus B.
