I can't get any menu with a sub-menu to expand

[lrubin28]

Somehow I killed my navigation menus!! Menus without sub-menus are fine, but I can't get any menu with a sub-menu to expand. What did I do?! Here's the first few lines (there's a bunch more but in the same format). Hellllppppppp!!!

<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td style="background:images/categories-bg.jpg repeat-x;"><img src="images/categories.jpg" width="217" height="41" /></td>
</tr>
<tr>
<td class="list">
<ul>
<li onclick="show_next('tab1')" class="tab_hover" id="tab1"><a href="/SiteIndex.htm">All Product Index <span class="icon"></span> </a>
<div id="tab1_data" style="display:block;"></div></li>

<li id="tab2" class="tab" onclick="show_next('tab2')"><a href="javascript:void(0);">Adhesives &amp; Sandpaper <span class="icon"></span> </a>
<div id="tab2_data">

I think the problems with your javascript, but you could also just do this with css for browsers other than IE. Then just write a script for IE browsers to get the hover state. I don't see a reason why it wouldn't, or would display with the code you posted though there's not enough. Post a link or all of it?
