The quickest way to get your Tumult Hype document displayed in your Wix site is to host it in your Dropbox's public folder, and include it as an iframe.
Of course, if you have a server you can host your Tumult Hype document on, use that.
1) Upload your site to Dropbox: File > Export HTML5 > To Dropbox
Click 'Copy Link' to retrieve the publicly accessible link to your Tumult Hype document
2) When editing your site, click 'Add HTML snippet' and paste in the following code:
<iframe src="http://dl.dropbox.com/spa/v8gf8flm4fo9tqv/Exports/yourdocumentname.html" height="400" width="600" style="border:none;" frameborder="0" scrolling="no"></iframe>
3) Replace the area within the 'src' field with your own document's URL, and make sure you update the height and width values as well to match your document.
4) On the page you want to add your document, click 'Add ons' at the bottom of the menu after you click the '+' button, and click 'HTML'. Select 'HTML Code' in the 'Mode' dropdown, and paste your code in the box and click update:
