Can't get playList array to print for anything?

I've looked at all the answers for the questions people already posted under this video about this problem but none of their solutions were the issue for me. It simply doesn't work, I don't know why. I tried to snapshot and fork the workspace, but neither of those functions worked so here is my code from workspace

var playList = [];
playList.push('I Did It My Way');
playList.push('Respect', 'Imagine');
playList.unshift('Born to Run');

printList( playList );

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

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

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Musical Playlist</title>
  <link rel="stylesheet" href="css/styles.css">
</head>
<body>
<h1>My Music Playlist</h1>
<div id="listDiv">

</div>
<script scr="js/helpers.js"></script>
<script scr="js/playlist.js"></script>
</body>
</html>

Hi Melissa, Your script scr declarations should be script src. This is causing your JavaScript files to not be loaded. Fix these typos and it will work.

Good catch, Dale. :+1:

I missed that because I loaded the JS directly onto the page to test it, which of course made it work just fine.

Thanks I missed that. Too obvious for me.
