Demo works, my site doesn't

The demo site works with my browser (Firefox and MSIE) but when I install on my site (www.jonesvalley.us) with your version 1.9 code, it does not. With 1.8 it DID work, but even now replacing 1.9 with 1.8 the timer does not work. I've even copied the demo source for countdown to superbowl -- works viewing demo site, does not work on mine. So I know that my browser configuration is ok, I have clean URL's enabled, the module is enabled, there are no permissions to check ---- what else could block the execution? Here is my source both for my timer and the copy of the superbowl timer:

<p>  
<span class="countdowntimer"><b><font color="red">Count-Down to Reunion 2008 . . .</font></b>
    <span style="display: none" name="datetime">2008-07-04T08:00:00</span>   
    <span style="display: none" name="tz_hours">-5</span>  
    <span style="display: none" name="dir">down</span>  
     <span style="display:none" name="format_num">1</span>
    <span style="display:none" name="threshold">7200</span>
    <span style="display:none" name="complete">It's Happenin' Now!</span>

</span> 

<p><b>Countdown to Super Bowl XLII</b><br />
<span class="countdowntimer">2008-02-04 18:25:00 -5 2</span></p>
