What have I done wrong, I've spent last 20 minutes staring at the screen. Please help.

var playList = [
  'I Did It My Way',
  'Respect',
  'Imagine',
  'Born to Run',
  'Louie Louie',
  'Maybellene'
];

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>';
  print(listHTML);
}
printList(playList);</p>

Hi Christopher,

Your problem is on this line:

listHTML += '<li>' + list(i) + '</li>';

And specifically the list(i). When indexing into an array, you use square brackets, not parentheses.

Hope that helps

Amazing thank you. Console said line 17 but I still couldn't see it. Thanks again.
