List missing during display even though exact code as Teacher

https://w.trhou.se/ns10yxzdxj

// square brackets = empty array literal var playList = [ ['I Did It My Way', 'Frank Sinatra'], ['Feel it Coming', 'The Weekend'], ['Lost in the Echo', 'Linkin Park'], ['In My Remains', 'Linkin Park'] ];

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

function printSongs( songs ) { var 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); }

printList(playList);

Anyone can help me spot any errors in my code? Its not displaying anything.
