Hey @tenzinrabjam! It might be best for you to contact whoever built the e-commerce functionality you’re using for support — it’s hard to know how to help without having the specific details about how the cart works.

It looks like you’re using WooCommerce? They have a support forum here: https://wordpress.org/support/plugin/woocommerce/ and support on their website: https://woocommerce.com/my-account/create-a-ticket/. They might be able to help you better!
