My output shows as one line rather than a list?

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

function playList (list) { var listHTML = "<ol>"; for (var i=0; i < list.length; i += 1) { listHTML += "<li>" + list[i] + "</li>"; } listHTML += "</ol>"; print(listHTML); }

print(playList);

print(playList) just prints the array which is why you see one line. You'll want to call your function instead. If you are following along with the video the function should be named printList. Then you would call it as follows:

printList(playList);
