What would be nice is if Paypal had a script generator so that you could input the information for your site and what you wanted the listener to do then have it generate the script you need. Any ideas on how to get a script for the listener that needs to be used for the subscribe button? I am not a programmer and so far no one has been able to help me in a language i can understand.
I am sorry you have not been able to find any answers about this. I would be glad to point in the right direction so see if you can get some help.
There may be some useful information about this in the PayPal Developer Forum. That is where discussions about customized solutions take place, and the people there are in the best position to offer you suggestions.
