Why isn't it printing anything on the screen

I can nog figure out why this code isn't printing anyting on the screen. Can someone help me?

var playList = [
  ['I Dit It My Way', 'Frank Sinatra'],
  ['Respect', 'Aretha Franklin'],
  ['Imagine', 'John Lennon'],
  ['Born to Run', 'Bruce Springsteen'],
  ['Louie Louie', 'The Kingsmen'],
  ['Maybellene', 'Chuck Berry']
];

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

Function printSongs( songs ) {
  bar listHTML = '<ol>;
  for ( var i = 0; i < songs.length; i += 1) {
    listHTML += '<li>' + songs[i][0] + ' by ' + songs[i][1] + '</li>';
  }
  listHTML += '</ol>';
  print(listHTML);
}

printSongs(playList);

You have a few things wrong, minor mistakes. For starters on line 14 "printSong function" you have the word function capitalized. Second on line 15 instead of tying var you typed bar Lastly on like 15 again you forgot the closing quotation after the <ol> tag. Hopefully that helps

Hey it happens. There's moments when I am doing a project and I can't figure it out and I just want to punch the computer. A second set of eyes always helps. Also I would recommend using the console on your web browser, a lot of times it will actually tell you exactly what the problem is
