Why isn't variant JS working on my Broadcast theme?

Store Design
1

Hi, I have an issue on my store built on the Broadcast theme.

Variant changes aren’t working, if you change the variant and add to cart it just adds the first variant. I’ve tried to step through the JS but it just seems like the code isn’t triggering at all, has anyone had this issue at all?

example - https://frp1josswbqdrozv-45809270952.shopifypreview.com/collections/all/products/cleos-paradise-body-cleanser

Any help or pointers would be much appreciated, I have recently taken the store over from another developer so unsure if he made any changes that would break the standard variant functionality.

Many thanks in advance,

Matt

I think it would be better way if you contact to the theme provider to ask for assistance
