The RSVP button is confusing to users because it does not explain that they have to first enter the number of tickets they want before the registration form is displayed. Since the count is initially set to 0, the form does not appear. However, if they press the “Confirm RSVP” button, an error message is displayed telling them they must enter a required value. But that field does not appear anywhere on the page until they change the 0 to another number.
One approach might be to set the default count to 1 so that the form is displayed automatically. However, this would allow them to enter a number greater than one. For our events, each participant is limited to one and only one ticket.
There needs to be an option to limit the ticket count to 1 and also to specify the default ticket count. Alternatively, we could remove the ticket counter entirely and simply display the registration form immediately.
