Hi,

I added a delivery date picker to the cart page in my shop and it does show up correctly. However, when I go to select a delivery date, it does not update in checkout when I select the shipping method and it doesn’t show up in order confirmation when I place an order. How can I fix this so the delivery date selected in cart carries through the checkout process and into the order confirmation page?

This is what I followed to add the delivery date picker to cart: https://help.shopify.com/en/manual/online-store/themes/themes-by-shopify/vintage-themes/customizing-vintage-themes/add-date-picker

Thanks.
