Did you put this:
<ul id='sddm'>
<li><a href='#'
onmouseover='mopen("m1")'
onmouseout='mclosetime()'>Home</a>
<div id='m1'
onmouseover='mcancelclosetime()'
onmouseout='mclosetime()'>
<a href='#'>HTML Drop Down</a>
<a href='#'>DHTML Menu</a>
<a href='#'>JavaScript DropDown</a>
<a href='#'>Cascading Menu</a>
<a href='#'>CSS Horizontal Menu</a>
</div>
</li>
<li><a href='#'
onmouseover='mopen("m2")'
onmouseout='mclosetime()'>Download</a>
<div id='m2'
blah blah in the functions.php?
