ActionScript 3.0 :: Cannot Embed Multiple SWFs Into HTML File

The site referenced can be found [URL] I need to embed multiple .swf files into an html file. I
prefer using swfObject. Here's what the code looks like now:

<!-- l4dt_header.swf start -->
<script type="text/javascript">
var flashvars = {};
var params = {};
params.menu = "false";
[Code] .....

What happens is one of the embededd swfs ends up overriding the other. I also need the rotating movie clip to pulse, on and off, and bright lime green. I'm aware of the glow filter in actionscript 3,
filters = [new GlowFilter(0x5d7c00,1,6,6,2,3)];,
but how would I get it to pulse?

Then if you go to the site [URL] you'll see a green cloud as that is part of the swf. I want to create the same toxic warning symbol that is rotating in the center, but much smaller, and multiple instances of it, flashing in and out at random locations in the green cloud. Then I'll be creating a Flash App where a user can can layered "posters". Is this code sufficient for allowing the user to be able to move those individual layers in perspective to the whole
App?

MC.addEventListener(MouseEvent.MOUSE_DOWN,
function(evt:MouseEvent):void{
MC.startDrag();
});
MC.addEventListener(MouseEvent.MOUSE_UP,
function(evt:MouseEvent):void{
MC.stopDrag();});
