By default, EventCreate collects data from all Attendees. This includes all required form questions.
Under the Advanced Registration settings, you can select who you want to collect data from. To edit the Data Collection, go to Setup > Registration > Advanced and choose your preferred method.
The data collection methods are:
All Attendees - all persons attending your event
Registrant and Attendees - the person filling out the registration form plus all persons attending your event
Registrant Only - the person filling out the registration form
If you choose to collect info from the Registrant Only, any standard or custom form questions will only apply to the Registrant. You will not be able to ask questions about the Attendees.
When you collect info from the Registrant Only, all answers to standard or custom form questions will appear under the Orders/Registrations Report.
