Set price depending a membership list

I need to make a registration form for an association´s event, which will receive attendees which are members and not members, but depending if they are members or not they will be charched differently.

Is there a way to have a list with the emails or member number to check from and see if they are members and if so charge x amount and if not in the list, charge another amount?

And if it is not too much to ask, within the memberships there will also be different prices, which can also be set on the "hidden" list, can that be included too?

thanks

I'm sorry, but the list lookup is not possible in the form.

As for the price based on the membership type, that is possible. You have to setup the price based on a conditional logic. But this method requires you to use either the dropdown, radio or checkbox field instead of the payment integration.

Here's an example form: https://form.jotform.com/60376369472969 (Select Basic and Product A) to see the total.

Here's how you can forward the total to payment integration: http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field.
