Is it possible to enter in the registration form an opportunity to be able to choose the type of member the registrant wants. I want 2 choices.
Yes, you can do that…
You can give him the two PayPal buttons on the same page to pay the one he wants. Or you can link to separate pages for the options, each with its button. After paying, they need to register, or you can let them register free first, and then upgrade with the payment.
The s2Member Pro form handles the registration and payment. And with the pro-form you can give the two options on the same page, or you can link to separate pages each with a pro-form. https://s2member.com/kb-article/how-do-i-display-multiple-checkout-options/
Does that help?
