proceed to checkout not working (Still)

Retarded. That's all i can say. My update for this is that I figured out how to get the proceed to checkout button working. I had to find the item that was in my cart that was causing the problem. In my case, I had Crayola Classic 64-count Color Pack Crayons, 2 Pack in my cart. Once I removed it, i could proceed. No error - no failure - no "this item is not available" just a white screen and back to the cart. Walmart support is also no help. they contacted me and wanted to know what my order number was, which i didn't have because - guess what - YOUR FRIGGIN SITE WAS NOT WORKING!!!! Moral of the story, forget support - if it's broke, start over and see if you can get past the problem.

THANK YOU!!! I have been trying to check out for over a week now, contacted Walmart several times, still couldn't figure out WHY I was unable to proceed to the final check out screen. Found your message online and sure enough, I have the Crayola Classic 64-count Color Pack Crayons, 2 Pack in my cart. I removed it and hey presto..able to check out!! Good grief!! Thank you again for saving my sanity..I swear it was starting to slip!
