I only get one number

I only get 1 undefined to list on the page, i cant find the problem. What is it i am missing?

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);

I see one semicolon which is not supposed to be there.

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

Also try to wrap your code in three backticks so it is easier for everybody to read and answer your questions. Now your code is very difficult to read and maybe i didn't spot all the errors.

Happy Learning ;)

also you forgot to close the ol tag which I think is causing your program to break ... istHTML += "</ol"; print(listHTML);
