How come when I try to add to this array, and preview the screen, it is blank?

I've completed the coding and it works but how come when I try to add to the playList array, and preview the screen, it is blank? I thought the list.length property automatically detects how many items are in the array? Thanks !

Hey Mike - Forgot to add a comma after the "maybeline" Thanks for trying to help! Answered my own q.

:)

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

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);
