I'm really happy with my custom list application. You can see it on these 2 pages: http://bobfreedmanarranger.com/probigband.aspx and http://bobfreedmanarranger.com/hsbigband.aspx.
This gave me the control over my digital downloads store so I can generate the product listing with "Add to Cart" and "PDF Preview" codes.
I couldn't have done it without the forums and blogs....Thank you!
