function print(message) {
  document.write(message);
}

function printList( list ) {
  var listHTML = '<ol>';
  for (var i = 0; i < list.length; i += 1) {
    listHTML += '<li>' + list[i] + '</li>';
  }
  listHTML += '</ol>';

Okay, Ian. Could you do us a favor and take a snaphot of your workspace and post the link here? See my image for the location of the snapshot button in workspaces. snaphot

Just copy and pasted both of your files and, it works perfectly. No errors. Maybe need to refresh the browser. You can always check for errors as well in the browser. Using chrome it would be command + option + J on the mac...for example.

Elian above mentioned the name of your .js file and that appears to be the only other thing that we can't visibly see but, could be causing a problem.

Sorry, it's my first time using the forum and I think it deleted my code. I meant to ask if there is a script src linking your javascript file in the html.

Good one! That's probably it. I deleted the other question for you. A tip for future use, you can post an asnwer and a comment. If you have a small question like the one before, it's probably best to use a comment. If you have an answer ready, it's best to post an actual answer.

And welcome to the community!

Same goes for Ian, by the way. Try to use comments if you do not have an answer ready or are just replying to a given answer.

I already checked the script tag in the html and it is indeed linking to the correct .js file

I must admit I'm stumped. Would it be possible to post the HTML as well? My only guess is that perhaps one of the tags needs closing.

Can you post your HTML here, Ian? Or provide us with a snapshot of your workspace?

Your HTML is fine, as well. Are you sure your js file is named "playlist.js" and that it's located in your js folder?

JavaScript was a window.print() method, which could mean it's a protected function name. Otherwise, I'm clueless.
