Thanks for reaching out and pointing me a possible error on my tutorial there, among other few things I should probably fix.
You see, I'm no longer working with my now dead "your-home" project (although I am currently looking for a job), and these tutorials were part of it.
There's also only so much I can do without at least a link to the website.
That being said...
jQuery not loaded
This means the script couldn't find your link. Probably you didn't use your own video id there:
Everything in red there, within the quotes, should be replaced by your own unique video id. And that will be different if you're using youtube, vimeo, wistia or whatever.
I've just updated a couple pages accordingly, with a few things fixed.
