When adding seat variables to your email, for example:

• ${event.seats.seat.name}
• ${event.seats.registrantnumberreserved}
• ${event.seats.totalpercentagereserved}

You must wrap these variables between @list_seats and @end_list_seats otherwise the app won't know how to output these variables.

For example, do this:

@list_seatsSeats: ${event.seats.registrantnumberreserved} seats for ${event.seats.seat.name}@end_list_seats

Instead of this:

Seats: ${event.seats.registrantnumberreserved} seats for ${event.seats.seat.name}
