Hi I installed and it's working but I have an issue. My starting price is 0 and in that case the addon does not work. I have the option to fix to starting price to 1 and it will work but I will need disable the add cart when the price is 1. How to disable the button "add to cart"? Something like "if the price > 1 then addtocart=true else =false. I'm not good on php and I need help to fix the issu.
