Find a duplicate value within a list?

I am trying to create a simple formula that finds and displays any duplicate
values in a list. I figured this should be easy to do, but I can't find
anything that will perform this action for me! Help!

In a Helper column, use this formula

=COUNTIF($A$1:$A$100,A1)

Then Data/AutoFilter on that column to show rows with numbers > 1.
