Problem with finishing order

[minap]

Hello,

I am out of ideas. When I put something in the cart, I click on Checkout on www.cokeboys.cz, there is an error:

Message: Access denied
Line: 138
Character: 355
Code:0
Identifier URI: http://www.cokeboys.cz/js/jquery/jquery-1.4.4.min.js'>http://www.cokeboys.cz/js/jquery/jquery-1.4.4.min.js

When I click inspect element on "finish order" cash on delivery payment there is an error:
XMLHttpRequest cannot load 1305118693065&ajax=true&token=c65e5930a767a12096c7406d05979662 >http://cokeboys.cz/cart.php?=1305118693065&ajax=true&token=c65e5930a767a12096c7406d05979662. Origin http://www.cokeboys.cz is not allowed by Access-Control-Allow-Origin.

My customers can´t proceed and finish the order.

Anyone know what is going on?

Please help.
