document.getElementById(msg) is null

Hi....I have an error in my script, but idk where it is..... here is the script:


<script type="text/javascript">
var browser = navigator.appName;
if (browser=="Netscape") {
document.getElementById(msg).style.display="none";
}
</script>
<div id="msg" style="width:100%;padding:3px;position:fixed;top:0px;left:0px;background:red;">Please install <a href="http://www.mozilla.org/sk/firefox/">Mozilla Firefox</a> to view this page normally.</div>

document.getElementById('msg').style.display="none";

also the script block should be after the div element in this example.
