Help with script

Looking for someone familiar with rss 2.0 to help me get the McJiffy script working. An example of my site is popularparking d0tcom When you click on a product link it just goes to the main ebay page instead of the product page. An example of a working site is zapcheap d0tcom. I don't think it's a huge job maybe an hour or so.

Let me know what you think.

Paypl payment.

although i'm not familiar with the script, if i see the different between the site is, only in the campaign id in encode url.
has you setup the campaign id and App id on default.php?

Fixed, campain id was in wrong spot. Thank you for pointing it out.
