Want fixes on my website pop up payment & fake clicks/bids

Hi, My site is: [login to view URL] Here are the jobs: 1. i want that pop up thing always show me user's email ,whenever i click the buy button the thing is that it only works one time everything you login then it don't show until you log out and log in again. My 3 payments processors are now working properly, but it needs this fixes, I have paypal, alertpay, google checkout. So when they login they don't have to need to logout and then login again so it shows the right amount on buy clicks 2. Some times when use the clicks and then click then try to buy clicks and then click the back button on your button the fake clicks appear again without even bought them. I will pay $30 max for this thanks
