I’m wondering the same thing. I defined it on the image itself but still no bueno. I’m assuming we’ll have to edit the javascript. Hopefully you can get back to us or I’ll have to think for myself.
I was having the same problem with the sku deal. I then, added 100 total to the # that was in stock for that particular product. I’m guessing that if you give a product a sku # without specifying how many you have in stock…it assumes that it’s out of stock and you shouldn’t be allowed to add it to your cart in the first place. Could be right could be wrong but it works if you bump up the inventory.
cheers
