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

You forgot to add end of the function printList(list): print(listHTML); So your function should look like this:
function printList(list) {
var listHTML = '<ol>';
for (var i = 0; i < list.length; i += 1) {
listHTML += '<li>' + list[i] + '</li>';
}
listHTML += '</ol>';
print(listHTML); // You need to add this line on your code
}
printList(playList);

`var playList = [ "I Did It My Way", "Respect", "Imagine", "Born to Run", "Louie Louie", "Maybellene" ];
function printList(list) { var listHTML = "<ol>"; for (var i = 0; i < list.length; i += 1) { listHTML += "<li>" + list[i] + "</li>"; } listHTML += "</ol>"; document.getElementById('insert-id-tag-here').innerHTML = listHTML }
printList(playList);`
