Feedback from 3rd party shopping cart software - why the html isn't working in your new homestead software

Homestead did correctly identify the problem, the View Cart button is being embedded in an iframe and that's why it vanishes when you click it. Basically, the frame it is in is the size of the button and so basically you're seeing the cart through a tiny keyhole rather than seeing it appear on your page as intended.

Unfortunately they misidentified where that iframe code is coming from. It's not part of our buttons at all, it's an aspect of their site design software. I'm really surprised that they'd send you to us to ask for some different code, because if they are the ones adding the iframes to your site there is literally no different code we can give you that will change what they are doing. The best we can do is give you code that bypasses the issue entirely by opening our cart in a new window rather than the usual in-page overlay display.

This particular cart code works just fine in your old desk top version of Site Builder...and you can't get it to work in your new build! Something is very wrong!
