How do I list ONLY duplicate cells? Please help :) I have an example listed! 
Thank you very much for your help in advance!!
I am trying to create a column (see D), that lists ONLY duplicate instances of cells from another column (A:A).  For example, I am trying to recreate the results of column D.  
Column D should only list results from column A:A that appear more than once.  Thus, the data from from A2 does not appear in column D, as A2's data was only listed once.
Thank you to any who can help me!! :P
