Submit Order Button Sends to Billing/Shipping Page

[jontaco]

Hi,

A customer informed me that she unable to complete an order through our web site. She said that everything in the shopping cart was fine up until she pressed the "Submit Order" Button on the Review Order page. I confirmed that her order did not carry through to Shopsite. She was using IE.

I looked into it and found that the only versions of IE that were doing this were Internet Explorer 7 and 6.

Each time i tried to order an item, I would get all the way to the page where I reviewed my order. Then when I pressed "Submit Order" I was taken back to the Billing/Shipping page. In every case the order was not sent through.

Oddly enough, I tried IE 6 and 7 a few minutes ago and they are both completing orders now and I am taken to the thankyou.cgi.

Any ideas?

Thank you,
