Javascript Error - Any help appreciated!

I'm trying to impliment a dropdown navigation menu for those
who visit my site and can't make use of my Flash banner navigation
menu.  I'm not sure if I've lost my mind or what, but the thing just
will not work.  IE gives me an error about document.navForm.navLinks 
is null or not an object.  If anyone sees the problem, I would much 
appreciate the input.  Code snipped pasted below, and thanks again...

<td> 
       <form style="paddingleft: 40px; margin: 0px; name=navForm">
        
              <div align="left">
                <select name="navLinks">
                  <option value="http://carpet-sharks.kaslwebs.com/index.html" selected="selected">Quick Navigation</option>
