checkout not working

--www.inkdroparthaus.com
-- HikaShop Business: 2.3.1
-- Joomla! 2.5.18

Just upgraded to latest HikaShop and now the checkout will not work properly. This is what happens: After adding to the cart, filling out the address hitting the next button it redirects to the home page. No error messages. I read in another post that it is a js issue. Not sure what to fix in the code so I made a screen shot for you to take a look and let me know what I need to change.
Thanks
