Q: Some of the attendees using the same email address to register to my event, how to prevent this from happening?
A: You can setup email address field as a unique value field.
- You can mark email address as "Unique Value" - No duplicate
- If the attendee already uses their email once to register for the event, if they try to register again using the sam email address, error messages will appear as below:
- A message informs the attendee how many errors within the form
- Message at the error - in this case, "Email is duplicate". In this case, the attendee will have to change to a different email address in order to continue completing the registration.
Similarly, if there is any other field you prefer to have no duplicated information, you can utilise this option.
