One way...

Use a helper column to mark the duplicates.

Enter this formula in column D and copy down to the end of data:

=IF(COUNTIF(C$2:C$20,C2)1,"DUP","")

Then apply AutoFilter and filter on column D = DUP

If you could help me with this it would be greatly appreciated.
Column A Has client codes
Column B Has client names
Column C Has client addresses
The same address may be used for multiple client codes. I am only
looking
for duplicate addresses. What I would like to end up with in my report is
only the lines that have addresses that are listed more than once. If
an
address is only listed once , I do not want it to show on my report.
Thanks
