Shopify Buy Button JS - Product Attributes not being passed

Hi everyone

I have the Shopify Buy Button JS working great on our website. It is music products that shows products names, but not the artist names. The artist names on the Shopify store seem to be called Product Attributes and in the source code are "product-attribute__value”

Can anyone tell me how I pass these values over to the Shopify Buy Button JS on our Wordpress site? There doesn’t seem to be any way of doing this that I can see.

Many thanks!

Bob

Thank you very much for the reply. I think Shopify are missing a trick here!
