Product Configurator: addToCartButton don't work

I am setting up a website (look at it here) (it is in Swedish but you’ll understand the concept) where the customer can choose what color and what “Patch” (an accessory) they want to have on their personalized laptop case. I have managed to use this article to create the color and patch picker but I cannot get my “add to cart button” to work.

I know that this has been an issue for others and that product configurator and other Corvid stores have issues and I hope that there is someone who can help.

If anyone has encountered the same problem or someone can give me a hint of where I can start troubleshooting, it would be much appreciated!
