Crystal Reports Report Footer Indicator?

Message

     Hello.
I need to modify an existing report to include a summary/footer text box that indicates the presence of a specific value in the data. 

ie: if 'Bob' is in the recordset of first_names, then have a single line on the report that reads 'Bobs in the list'.

I am a programmer by profession but this is my first task with Crystal Reports.

Thanks for any attention to my question.

Ken
