My code is exactly the same as in the video but it wont print my list to the screen... can you see what I did wrong?

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>"; console.log(list); } listHTML += "</ol>"; } printList(playList);

Hi Dawn Baker ,

You were very close but just missed include the print function inside the printList function.

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>";
    console.log(list);
  }
  listHTML += "</ol>";
 // Add the print function that will output the listHTML
  print(listHTML)
}
printList(playList);
