I'm trying to write a macro that will filter out duplicate entries in a
column so that I can use the entries in that column to populate a combobox.
Here's an example of what I'm trying to do.

A
A
B
B
B
B
C
B
A
C
C
D
D

I want to filter the above data using code so that the end result is:

A
B
C
D

This doesn't seem like it should be that diffucult, but I'm having problems.
Maybe I just need a nap.

Anyways, any help provided will be much appreciated.

Thanks,
Jason
