Questions should not be added or removed once people have started registering for your event. This can cause issues with reporting.
Contact Information question set is a reserved name and cannot be reused. The Contact Information question set cannot be removed or edited.
Question Sets can be added directly to your event as well as added as a user-reusable question set when not created from within the event. Note, this does not effect copying your event.
Question Sets can be added to your event in two places.
The Transaction Question Sets are asked once per registration and appear near the bottom of the registration form.
Quantity Question Sets are asked once for each quantity the end users specifies. They are asked near the top of the form and are grouped together.
A good use of the quantity question sets would be too ask attendee information.
You don’t need to create any question sets or create multiple ones, it just depends on what information you want to gather. We recommend creating a test event on the test site to see what things will look like and avooid cluttering up the production site.
As long as no one has registered for your event, you can remove and edit your question sets.
