conditional statement in html not working

I can't seem to figure out why this snippet of code is picky.  When I place it in most places within an html page, it does not work.  However I did get it to work in one seemingly random spot.  Is there something that I should add before and after to allow me to place it anywhere and work?  

The below code displays a message to non-IE users
<!-- [if !IE]> -->
		This browser is not supported! Please use Internet Explorer.  
 <!-- [endif] -->

To begin with, it's not formatted properly.

<!--[if !IE]>
     This browser is not supported! Please use Internet Explorer.
<![endif]-->

Only Internet Explorer support conditional comments, all other browser ignore such things.  You will have to use javascript browser detection to inform the other browsers.

if I use the exact code you provided, both IE and Mozilla are ignoring it.

All browsers but IE ignore conditional comments, they treat them as just plain comments.  And your statement [if !IE] tells IE to ignore it.  You have to use a different method.

Sorry, but your code always displays the statement in both browsers...shrug?

@ DaveBaldwin
Yes, this is what I want, a statement that IE will ignore and all other browsers show the statement!

You probably need to use javascript:

var isIE= (/MSIE (\d+\.\d+);/.test(navigator.userAgent)) ? true : false;
if (!isIE) document.write('You need to use Internet Explorer fot this page');

Or do it properly by detecting on the server and send a page with just the message instead of wasting bandwidth sending the whole page.

For the server side in PHP:

(eregi("MSIE", getenv( "HTTP_USER_AGENT" ) )

for ASP:

InStr(1, Request.ServerVariables("HTTP_USER_AGENT"), "MSIE")

not sure why, but if I place this immediately after the header and nowhere else it works!

example...
<body style="background-color: #FFFFFF; background-image: url('')">
</body></html>

<!-- [if !IE]> -->
		This browser is not supported!&nbsp;&nbsp; Use the &quot;Internet Explorer&quot; 
		shortcut on your desktop to start NextGen.
 <!-- [endif] -->

sigh...that was fun...and annoying

this is the right code, but requires spaces before the dashes.  I was able to get it to work by placing in a specific place in html code.  It is also unstable, and does not always work depending on network conditions for some reason.  

I am abandoning this idea, will search for another way.
