Webflow CMS Integration, Variants, Digital Downloads

I could really use some help! I’ve been working on this website design for too long. After making a few changes incorrectly, I’m now lost and cant wrap my head around how this needs to be configured in Webflow, or what is the most efficient and optimized solution…

I want to make a “pay what you want” option for digital download products.
to accomplish this, I made Variants in the products CMS to list options and have the price reflect that selection:
1[+1.00]|2[+2.00]|3[+3.00]|4[+4.00]|5[+5.00]

This is what I want to accomplish in the design:

  1. On the product details, I want the customer to see and select “Price” options and there, which would update the cart

  2. Remove quantity from the cart

Here’s my live site:
