Can someone help me find the problem?

Hi. I can't find the error in this code. Nothing is happening when I run it.

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

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);

Your for loop comparison operator is facing the wrong way.

for (var i = 0; i > list.length; i += 1) {

should be:

for (var i = 0; i < list.length; i += 1) {

You want to keep going while i less than the length of list.

You can also make it a little shorter using i++ at the end:

for (var i = 0; i < list.length; i++) {
