I removed INVALID_URL all together. There were some issues with certain users not having something enabled on their browser to allow their browser to pass the reffering url. So it will no longer be a problem.
As I wxplained in an earlier post, I will not remove or change the INVALID_ITEM as it servers a purpose for some users that enable this script on a page and call it weather or not they are showing a valor item. I want to make sure there is no unnecesarry volume on our servers that may affect the performace for your calls to the script.
