Need help with product options configurator

First of all, thank you for reading this post.
I am working on a client’s website where I have to deal with 6 custom product options.

I am new to custom product options so I thought I’ll do a test run with the following code:
the page- https://www.theboxkeeper.com/diwali-box


The 6 test product options:

  1. Diya- Diya, No Diya
  2. Cush- Cush, No Cush
    and so on…

The problem I’m facing is that I run the above code, the console logs “Product added” but the cart is still empty. I have checked and rechecked the following and there are no errors-

  1. Product Code
  2. Product options and the option names.

There are no custom text fields in the product.

Any help is appreciated. Can’t wrap my head around where exactly I am going wrong, been at it for hours really. I’ve read all examples and code references.

UPDATE: this has been solved now. For some reason adding a new product worked but it still doesn’t work with the old product.

Don’t suppose you know how to add more than 6 product options?
