Ok, so here is what I found, on the checkout page the states and countries are not listed from the database but statically on the page for the option list and this is where the "US" is coming from. In the DB US was listed as USA, even when I changed it it still did not work.
Would I be correct it deleting the static listings on the page and telling the drop down to list its data dynamically from the database?
Also how do you get the system to generate order numbers?
Thanks for your help guys once this works I will be ready to launch!
