Loop name to get custom code working with pop-up

Similar to Janke’s question, I also like to know the loop name or any help you can give to those of us who need to add custom code for our customers ??

I’ve got a script that updates the total price shown on the product page when the user changes the quantity. Sadly, I can’t seem to get the script to fire in the modal.

Click on a product on the homepage “View to add”; modal opens and you can see the “Total:” text on the right of the “Add to basket” button. The script is from: https://www.businessbloomer.com/woocommerce-calculate-subtotal-on-quantity-increment-single-product/

Happy to pay and or buy the premium plug-in! Merry Christmas.
