Thanks. But I don't quite understand how the Progress Field helps in this actually.
Main purpose is for registered users to first login, check/update their profile, click "Update", then a Thank You Page or message shows to user.
In the same message/page, it should be able to display a link to the article with PayPal button.
What I require is a seamless process where the user could login, update details if necessary, then proceed to make payment for their subscription.
All I would require, would probably be somewhere which the page could display a thank you message, and embed a link to the payment page.
Is there a script file in which I could amend the message after the "Update" button is clicked?
