When a registrant wants to add a guest the following steps need to be performed. First, the registration for this person will need to be canceled. Then they will simply need to register for the event again with the proper information. Below I have included a step by step process to complete the cancellation of a registrant.
To change a registrant to a Cancelled status:
1. Open the dashboard for your event.
2. Click "View / manage registrants" on the right-hand side of the Registration section (see image below).
3. Choose "Registration" from the first drop-down menu.
