Need help getting custom CSS to work.

Hello Thimo/All,

This is the link to the store I am helping set up at the moment: http://porphyraband.com/swag/

It seems that any time you add something to the cart that seems to be out of stock at Spreadshirt (in my case, the first item in the store – the black mug), the “Add to Basket” button changes to “Add Failed,” with no other explanation. I am assuming that this is because the item is sold out because the red and blue mugs can be added to the cart. Can something be done to make this produce an “Out of Stock” message instead?

I have a few CSS issues as well, but I will address these in a separate post if I cannot solve them myself.

Thanks much. This is a great plug-in!
