Not Getting Any Output in Preview

I believe that I followed along with what Huston was doing, but I'm not getting any output when I preview this. I have included a snapshot of my workspace below:

Without forking your snapshot, I spotted a couple of potential issues right off:

  • your HTML tries to include a script file "hello-world.js", but there is no such file in your snapshot
  • there is a stray equal-sign (=) in the type attribute of that same script line

Thank you, I am relatively new to this - Hopefully, I'll be able to catch the next one on my own!

Nailed it. I had the same problem for a bit and was hitting my head against the wall. Watch the bit where he talks about scope again. You'll hear him mention that the scope of the mainCtrl controller is limited to the div that it is applied to. This means that for your helloWorld() function to work IT MUST BE BETWEEN THE TAGS that you applied ng-controller="mainCtrl" to. Or simply: in your index file, cut the content on lines 18-24, add a line between 15-16 and plop it there.
