Hi @backhome84 
Thank you for waiting!
I’ve checked your widget and see that you’ve already added a PayPal button to your widget. Also, I see that you’d like to complete the payment before registration and my colleague Natalia has contacted you in a support ticket.
As she mentioned, it’s impossible to track if the payment was made and redirect the visitor back to finish the registration form. However, we have a similar request in the Wishlist. Feel free to vote for this idea
