    I don't know whether this is too advanced for JotForm and better fit for programming a form from scratch--- but I have a registration form for a fundraiser where I have two prices available for purchase to choose from via Paypal (Non-Attendee and Attendee Prices) The "non-attendee" price is $15 while the "attendee price is $10. 

    In order for the user to pay the lower $10 fee, I want the system to check whether that user has already registered for the general conference itself (I have a SQL table of the registered users) Is there a way where the form can check if that user is already on the SQL table of registered users before applying that amount?

    Any kind of code I can inject or is that too advanced?
