Thanks, I was able to figure it out with your help. I didn’t have a blank template for the cart.
I don’t remmeber where I got it from, I think it was from the treasurechest site. I removed the js include line, because it would add it the js dynamically, so kept adding 2 products.
I also added the [*#content*] tag you can see at the end
I modified the resource to include this only
[[TreasureChest? &item=`1`]]{{productinfo}}
but the PHs can be added into the template too.
so if anyone else is having these issues, maybe this will help
