How do I add a new attendee to an existing order?
Each attendee belongs to a single order. An order can have one or more attendees and you can add/delete attendees as appropriate. Your customers can also add attendees to an existing order by following the link provided in their confirmation email
Go to the order record which you wish to cancel
Select which event the new person will be attending and click "create attendee" to create the new booking
Initially the dropdown list will only include events still open for registration. As a logged in administrator, you can book a person into any event within your account, even if registration has now closed. To list all events, click the List all events link, then proceed as above.
