I just checked out your video. From what I can see you’ve added the href/link to the div, but it should be added to the first – <a>. So add something like this for example –
<a href="http://link_to_your_site.com">Text goes here</a> just replace the link_to_your_site.com part to your own link and it should work.
I just updated the code from that page to make it a little easier.
