You can select the entire Column and use Conditional Formatting (Home Tab) -> Highlight Cells Rules -> Duplicate Values...
This will highlight the duplicate values

Before that, you can sort the data alphabetically to see the number of occurance for each name.

Hi Tonya,

If you're still working with excel 2003 and want a formula solution, then you could do the following:

Since column C is blank:
cell C2: =IF(A2=A1,1,"")

Drag this formula down.
Now apply autofilter.
First alphabetize column A using the filter.
Goto column C's header and choose to show 1.
Now remove all the rows that are still visible.
Finally remove all filters and the formula's from column C.

Best regards,
Trowa
