Hi I'm trying to open a webstore made in Wix. Process like, when a customer already decided what's to buy, the color, quantity and more and it has a upsell just like the page below ---> https://getcarbonklean.io/offer-01/?lpid=512&utm_source=5385&utm_medium=rdr&utm_term=21584&utm_content=321&utm_campaign=GU&aff_id=5385&camp_id=21584&sub_id=rdr&req_id=306054089&contract_id=689&oid=498 and check out/pay in shopify! Please let me know if it's possible here in Wix.

I have five (5) checkbox fields. I would like to make sure only one checkbox can be ticked and get the value of that checked checkbox.
