PLEASE HELP SOMEONE

I need to figure out how to:

I need to have the totals at the bottom be corresponding with the current input by the customer.

  • Cost per item is (cost of drinkware + sum of stuffers+cost of hangtag)
  • Cost of items is (Cost per item) x quantity
  • Handling is
    -if ship to one address is checked (quantity/32 rounded to next whole number) x 12.90
    • if ship to multiple addresses is checked (quantity x 4.90)
  • Shipping Estimate is:
    • if ship to one address is checked (quantity/32 rounded to next whole number) x 48.98
    • if ship to multiple addresses is checked (quantity x 17.75)
  • Total is (cost of items + handling + shipping + credit card processing fee)
  1. Wix has a payment button, which I want to be able to modify to be the amount of the Total. I found an article.

  1. Need to set: “if ship to multiple addresses is checked, make the upload address list button required” “If ship to one address is checked, make the shipping address fields required”

  2. If there is a way to connect all of the content to databases so I do not have to update every page. I would need databases for drink ware stuffers, box stuffers (which have not been added), basket stuffers (which have not been added).

Any help would be much appreciated.
