I did exactly what you have instructed me to do. Now the 'buy now' tabs I have on my sites looks exactly like the Paypal buy now tabs instead of ejunkie's buy now tab.
However there was something missing when customers made a purchase by clicking through my newly created 'buy now' tabs. After the payment is completed and processed by Paypal, normally the transaction will be recorded on a page which can be accessed in my Paypal account (by clicking details of the transaction) and the details (name and address) of the customer would be available to view, but not with customers who used my newly created 'buy now' tabs to make a purchase, instead when I access my transaction page I only find the quote 'We have no postal address on file'.
It seems like the customer wasn't taken to a page to fill in the details before the payment was processed. Is this skip normal with ejunkie's buy now codes?
I need to mention, this didn't happen with ejunkie's add cart codes.
