You don't say which version of swf object you are using, but if you are using 2.1, and dynamic, here is how you would do it:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<!-- saved from url=(0014)about:internet -->
<html xmlns="
http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>My Web Site</title>
<script src="swfobject.js" type="text/javascript"></script>
<script type="text/javascript">
var flashvars = {};
var params = {};
params.bgcolor = "#E6FFDD";
var attributes = {};
attributes.id = "myIntro";
swfobject.embedSWF("swf/myIntro.swf", "myIntro", "149", "250", "8.0.0", false, flashvars, params, attributes);
</script>
<script type="text/javascript">
var flashvars = {};
var params = {};
params.bgcolor = "#ffffff";
var attributes = {};
attributes.id = "header";
swfobject.embedSWF("swf/header.swf", "header", "960", "250", "9.0.0", "expressInstall.swf", flashvars, params, attributes);
</script>
<body>
<div id="header">Content for users without flash - the header will appear here</div>
<div> More Stuff</div>
<div id="myIntro">Content for users without flash - the intro swf will appear here</div>
<div> More stuff</div>
</body>
Whatever version you are using, just be sure that each swf-div-id is unique.
