Annoyed with the SWFObject

I’ve been trying to make the SWFObject detection work and it’s not working. I followed the instructions on here: http://blog.deconcept.com/swfobject/

But nothing is happening! In the tutorial he also doesn’t say where in your page you’re suppose to paste the code into.

<script type="text/javascript" src="swfobject.js"></script>
		
<div id="flashcontent">
  This text is replaced by the Flash movie.
</div>

<script type="text/javascript">
   var so = new SWFObject("movie.swf", "mymovie", "400", "200", "8", "#336699");
   so.write("flashcontent");
</script>

I find the whole tutorial a little confusing. I am going crazy with this, can’t get it to work!

Anybody know of a more descriptive tutorial on how to make your browser auto install the correct, missing flash plugin?
