Prevent duplicate entries in a column.

[Angarsk]

Version: 2008 Operating System: Mac OS X 10.6 (Snow Leopard) Processor: Intel Hello.

I've been trying to find a way to prevent duplicate entries in a column:

I have a column for "Work order numbers" which are made of 2 letters and 5 digits (numbers). I need either to have excel stop anybody from writing the same Work order number twice in the column, or have a different column that shows something like "duplicate" if the cell is equal to other cell in the same column.

Thanks for your help.
