 * I’m not sure what I did as it was working fine then I started getting the number
   format error messages on top of my page. I reinstalled the plugin and added one
   item at a time but there are two corrupted items still in the cart with 0 amounts
   and I get that numbers error for each one on top. They do not show when I’m logged
   out of word press but when I add different items to my cart it adds the same 
   one over and over.

 * I figure it all out after a couple hours working on it. Cache issues and I also
   had 2 items with the same name that was causing problems. It’s back to working
   great!
