**abcmississippi**I have a registration form for a BBQ contest. They can select what type of registration they want and then they can add lunch tickets (0-15) as well. The tickets are $15 each. I have a calculation field in there that pulls the registration type but I also need a field to capture how many $15 lunch tickets they want and have it all calculate as well. Then will need to send this total to the payment engine.
