Hello Caroline,
Many thanks for being a rocking superstar here! I have used your code to code a product template. The main purpose was to add "addon" products for some products. I have implemented this via collections, for example - we have a product handle "product-handle" then I am creating a collection "product-handle-addons" and displaying those products as checkbox options under the main products. For example product: http://vapexperts.com/products/atmos-raw-junior-vaporizer has an mock option "G pen..." - when I checking checkbox - getting "Bad request" (gessing from Shopify). How can this be fixed? Here is my product template source link: https://dl.dropboxusercontent.com/u/163477/product.product-addons.liquid How can I make it adding "addon" items to the cart correctly?
Kind regards.
