Select whole record via drop down or grid

I'm just starting with phpRunner and trying to read (and understand) as much of the manual, videos, and article as I can. I have some ideas on my project but would like some more ideas, tips, tricks, or pointing in the right direction. The biggest issue is described below.

1. Database has three tables with two having a many - many relationship. Third table store the many - may relationships.
   
2. After a new event is added(Event Table), the people table will have records added by event registrars that do not know if a person has been entered in the people table during a previous event. Most will be new people to be added, but not all will be. People table will have thousands of records.
   
3. I'd to have People records matching name being entered displayed when the registrar starts typing in the name field. I see how to do that with fields, but need to display the whole record.
   
4. Then, if a People record matching the current input information is displayed I'd like the registrar to be able to click on the displayed record to add the PeopleID and EventID to the People-Event table and not add the People information again to the People table.
   The point is to not enter the People information twice and be able for the registrars to select already entered people from a drop down list or another grid. Then associate the people record with the event in the People-Event table. Any ideas on this would be appreciated. Thanks. PDB
