When an auction ends on my penny auction site, the PAY NOW button for the winning bidder doesn't work. I want this button to forward the user to PayPal with the correct total implemented. This button appears on the user's control panel and as a popup after the winning bidder wins an auction. I need the shipping amount and the auction total to be added together when the button forwards to PayPal. Then when the user pays for the auction, I want their control panel to reflect that it was paid. Maybe you can put a PAID text where the BUY NOW button is after it is paid.

I also want you to tell me which files you edit and add. I have another active auction site somewhere else that I want to update with these modifications. Thanks.
