Finish button does nothing when trying to submit API info

Hey Ray,

I know this was a problem earlier where you had to do a service ticket to resolve. I am guessing this is still the case as it's happening to me on 1.1.5 / DW 21.3

I have tried uninstalling/reinstalling the Freetools extension and also tried getting new API's from PayPal. Same issue.
I have also tried entering the API info in the eCart Payment Gateway Credentials screen. That will retain the info but I guess there's no connection between that and the PayPay > Payment Buttons for PP screen?

----------------------

Also, need your thoughts on if I can even use the "Payment Buttons for PP" or if I will need to use an eCart object instead. I am running a HOA and need to collect dues once a year. I have a database that I will use a PP Pay Now button that will allow the user to submit the payment from the database, I can use plain Buy Now buttons for that, however, I need to use API to get the info after the payment back into the DB after a successful payment to update the database. Can I use the Payment Buttons for PP to achieve this? Or do I need to create a cart in order to update the DB? The cart seems like overkill, but because I cannot get the API screen to finish, I wont know.
