What's wrong with this code?

TT Community,

When I preview this code it I get:

I Did It My Way, Respect, Imagine, Born to Run, Louie Louie, Maybellene

Instead of

  1. I Did It My Way
  2. Respect
  3. Imagine
  4. Born to Run
  5. Louie Louie
  6. Maybellene

Any thoughts?

=========================================

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); } print(playList);

Hi Zander could you place your code inside the markdown so it's easier to read??

It seems like the forum is removing the ol and li elements. You must invoke the printList() function, not print()

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);
