If you are familiar with SQL commands, I would a SQL statement like the following:
SELECT PrimKey, Count(*) FROM table WHERE Count(*) > 1 GROUP ON PrimKey

If you aren't familiar with SQL, then I would use a summary field and use the Group Selection formula to filter out data where the summary field =1.

Thanks that worked. I used the second part using Group Selection Formulas. I was not sure where to insert the SQL code in Crystal Reports. I am trying to make the switch from Access Report to CR. I am finding CR to be very nice to work with compared to Access.
 
Thanks,
Greg

Assuming you are still using Access as your data source, you would just create a query with the SQL in it.  You can base your Crystal Report on the query itself, without needing to refer to the base tables themselves.
