    Column A of my workbook has a series of serial numbers. I would like to be able to either highlight the cell of bold the text when a serial numbers has been entered more than once within column A.

    Thanks,
    Noir

    Noir,

    Try this conditional formatting

    =countif(A:A,a1)>1

    Suppose your values are in cells A2:A11, then use Conditional|Formatting -- put the following formula for cell A2

    =COUNTIF($A$2:$A$11,"="&$A2)>1

    Hope This Helps!
    Regards!

    Hi Brian:

    Your formula is short and sweet! and is better than mine.
