issue with people register multiple times

Question,

I am using the FREE Version of the plugin
after people RSVP for an event they are taken to a page
that does have their info on the top, but the RSVP form appears
again under that, and people keep filling it out and RSVPing again

… is their any way to not have the form appear again ?
people are getting confused by this, to me it easy but i’m a
computer person.

any suggestion idea’s would be appreciated
thanks
