Why isn't the free gift option adding to the cart on my live theme?

[sahilsharma4]

We are using free gift option in our cart which I have coded but when I am clicking Add to cart button it is not adding to the cart can someone help me out in this, My main concern is that same code is working on my draft theme, but when I am testing it on live theme it is not working at all. We need to fix it, can you please help me in this? The site url is: https://iloveskininc.com/ when you add a product greater than the value of 300$ you can see the free gift on the cart. and when you will add that button it is not working.

For the reference the same thing is working on this site: https://www.iloveskininc.com.sg

Can someone help me in this issue?

Hi @sahilsharma4 

I checked this, ajax cart submit is missing for the free gift product.

You have to write custom code for this.

You have to hire a shopify developer.

I can help you for this please contact me and share your store access.
