Excel 2010: Highlight a Duplicate Cell Value in another Column

Hello Experts -

     What would be the best formula to use in order to Highlight let's say a value in Column A and run it against Column D to see if that same value exist there.  If it does, highlight both values?  Thanks for your help!

Only problem with using conditional formatting as above is that duplicate values within a single column will also be highlighted, even if there is no match in the other column.

However, a couple of conditional formatting rules applied to each column can resolve this.

For the cells in column A, you'll have a rule like this:

This will highlight only values that are duplicated in the other column.  See the example workbook.
