If you are a User, instead of trying to update an RSVP, you will have to create a new one. My Invite Online only takes the latest reservation for each guest into account.
A New Reservation can be created as follows:
- Go to Main Menu --> Guest Management --> Guests
- View the guest whose reservation you would like to change.
- Add a new reservation by clicking on the +New Reservation button.
- Enter the information on the New Reservation form and click Save.
- As a result you will see the latest reservation with a light green background, indicating that this is the reservation that is taken into account.
