[jQuery] Adverts destroy my JavaScript

[[EMAIL PROTECTED]]

Hi there,

I noticed a problem while including layer-ads. Firebug says

"$("body") has no properties"

HTML:

<script type="text/javascript" src="{$path_js}plugins/jquery.js"></
script>
<script type="text/javascript" src="{$path_js}ajax.js"></script>
<script type="text/javascript" src="{$path_js}logoutScreen.js"></
script>
<script type="text/javascript" src="http://www.sponsorads.de/
script.php?s=116298"></script>

logoutScreen.js:

var Countdown = {
        timer: 15,
        stepSpeed: 1000,

        initialize: function () {
                if (!$("body").length) {
                        window.setTimeout("Countdown.initialize()", 500);
                        return;
                }
                $("body").append('<div id="logoutBox"></div><div 
id="toPortal"><span
id="countDownLine"><span id="countDownNumber">15</span> seconds until
logout</span></div>');
                window.setTimeout("Countdown.step()", this.stepSpeed);
        },
        ...
        ...

};

$(function() {
        Countdown.initialize();
});

-------------------------------------

How may I avoide this? I tried things like $.getScript() but it
doesn't work (and the ad-company doensn't allow it anyway).
Any Ideas?
