    Event RSVP Form

    Asked by guest_23057711759054 on November 01, 2012 at 07:51 PM




    I have two critical questions for an event RSVP form that I need to create:


    1. We will be handing out 600 invitations in print to specific people for an event. On the invitation there will be a QR Code that it will be scanned by the guests throught their smartphones to the Event RSVP Form.

    For security reasons we would like to input a rule in the Name Field to ensure that only the 600 people we invite can be register for the event. If the name is correct the form will be submitted, unless the form will be redirected to a page asking the responder to call the event organizer. Can I create this logic rule?


    2. How can I prevent repeated submissions?
