I had installed this feature and it worked great at first, however it has now stopped working. URL: https://perfumesonline.ie/ (gift wrapping option only available if item for Next Day Delivery selected and in cart)
I added the code to several other themes I have uploaded and it works on one, but not the others, so I know it's not the gift wrapping code at fault but must be a conflict somewhere.
Checking the tickbox does not update the cart.
When I inspect I get the following error: Uncaught ReferenceError: Shopify is not defined at cart:939
On another theme I get Uncaught ReferenceError: jQuery is not defined at cart:1408
