Unable to place an order..Looking for help!


I’ve created this e-commerce website using webflow for my client.
After adding several changes to the check-out page, the error message has started to appear when checking out and I have no idea why.

I’ve attached the read-only link below as well.
It’d be greatly appreciated if anyone could help me out with this!

FYI: Delivery item is set as a physical product, and Pick-up item is set as a service product since it doesn’t require shipping.

Here is my site Read-Only: LINK
