Well I hate to add to this mess, but just reading these responses is
definately an argument for the original post. This should not be this
difficult or complicated. Most users of excell are not programers nor have
the time to fiddle with long formulas to get an answer that should be easy to
get.

I suggest adding a COUNTU worksheet function that would automatically count
the number of unique data entries. It should have options for counting
numbers, numbers + text, excluding blank cells, etc.
