Dropbox video embed not showing on live site

I have managed to insert the code below to my website an it is showing up great in preview, but does not show the video on the published site.

Can anyone help me figure this out?
Is it the video format that is causing the issue? I am using Chrome currently to view the site.

Thanks!


Here is my site Read-Only: Webflow - WTX Development Co
