Assign a Value to a Duplicate Entry Within the Same Column

[Guest]

Within a single worksheet I have thousand-plus rows of data and one of the
columns within that worksheet I have a series of numbers. After I've
identified the duplicates within that column I want to assign a value based
on the first time that number shows up (in this case by I'v sorted by date),
so the first duplicate would have a value like "1." I then want to assign
the next duplicate(s) sequentially (2, 3, 4, etc.) When finished I would
want a new column of data that would have far more "1s" than "2s," more "2s"
than "3s," etc.

How do I accomplish this?

Hi,

Supposing Column D has those numbers (say, D22001, type in the following
formula in E2

=COUNTIF($D$2:$D$2001,D2)-COUNTIF(D2:$D$2001,D2)+1

and fill-in the formula down the column.

Hi,

Here is a simpler formula than the one I suggested in my previous reply (I
am embarrassed about the earlier round-about formula!)

=COUNTIF($D$22,D2)
