We're making headway here. There still are a few issues.
On the pp_confirm.php page I changed the store details to store the productName instead of the Name and that works fine.
1. The receipt that is sent by paypal doesn't include the Color or Size information.
2. The receipt sent from my site returns the error reflected in the attachment.
I've uploaded the screen capture of the error and the 2 files involved in the error.
