hi,
I've got a problem wiht addVariable (please take a look at the code below)

When I put two variables - swf presentation can't show on a webpage, when there is only one parameter everething is ok.

Did you have this kind of problem ?

here is the code:

<div id="HeaderZdjecia">
</div>
<script type="text/javascript">
var so = new SWFObject("header.swf", "mymovie", "950", "400", "9", "#ffffff");
so.addParam("wmode", "transparent");
so.addVariable("xmladress", "menurel.xml");
so.addVariable("id", "2");
so.addVariable("fv", "2");
so.write("HeaderZdjecia");
</script>

uff, I've fix it ;)

the problem was only in firefox and cause the error
An invalid or illegal string was specified" code: "12

I've replaced "&" --> "&amp;" in flashvars section
in my swfobject.js file and it works !!!
