Row Appended To Table Directly In Internet Explorer

I am making a web page, and as part of it I have a table that the user can add rows to. My code works in FF and Chrome, but IE is broken.
function addrow() {
var example=document.getElementById("new");
var addHere=document.getElementById("ticketTable");
var node= example.cloneNode(true);
node.id="added";
addHere.appendChild(node);
}
This code is called when a button is clicked. New is the ID of the row I am adding and ticketTable is the ID of the table I am adding to.
