Nothing is printing, can someone check my syntax?

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 1 = 0; i < list.length; i += 1 ) { listHTML += '<li>' + list[i] + '</li>';

} listHTML += '</ol>'; print(listHTML); } printList(playList);

I believe this question addresses the same problem

Basically, the browser behavior for document.write() has changed since the tutorial was written.

Keep on coding!

I found it, I had

var 1 = 0 instead of var i = 0.

Good job figuring it out even though my suggestion was wrong. When you post code, use markdown so it's easier to read in the forum. Here's how (see Markdown Cheatsheet for more):

Wrap your code with 3 backticks (```) on the line before and after...

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);
