Products disapear from cart when going to checkout

[SteinarAA]

My domain:

www.adamandeve.no

 

It works fine adding products to my cart - but once I press "Go to cart" - or in this case "Gå til kasse"; the shoppingcart turns up empty.

 

In the last few days I've tried changing the text on my buy button. I sais "Legg i kruv" - but I want it to say "Legg i kurv".

 

I think I might have messed thing up while doing this.

 

Anyone know how to fix?
