I'm not really a javascript/jquery coder, I have a very simple code to remove a div that's not working in IE

I'm using this in a Joomla page, so I call it like this:

$document->addScript(http://code.jquery.com/jquery-latest.js);//adiciona jquery

And than, in the body document:

<script>

    setTimeout(function() {

        $(#yourDiv).remove();

    }, 50000);

</script>

FireFox and Chrome are (as always) ok. Can someone point out my mistake please? Thanks a lot :)

EDITED ************

I've tryied also with this code no jquery, but always not working in IE (9)

<script>

setTimeout('yourFunction();', 5000);

function yourFunction(){

var div = document.getElementById(yourDiv);

div.parentNode.removeChild(div);

}

</script>
