I don’t have a Weebly online site, but I do have a couple of items I’m selling through online links. I’m having trouble finding those items to edit. 

When you click on the link, you go to a screen with a url that starts with "checkout.square.site/buy" followed by a unique character string.  The screen shows the item to be purchased, including a text description that I wrote. The item is a gift card, so I have sales tax turned off. 

But when I find that item in my Square inventory, there is no description, and sales tax is on. The link is the same link, so I know I’m looking at the same item. 

Question: how do I edit the item, including the description and the tax setting? 

Note: creating a link to a regular item in my inventory seems to be different than creating an actual "online item". For one thing, the link structure seems different. 

Can someone explain how this all works?
