I need some serious help with getting properties of a nested layer in 
Netscape 4.X.  The problem I'm having is that the outer layer contains a 
table in which I have id in the <td>s.  I have tried displaying the 
objects I get back from my calls and I keep getting "undefined".  Here is 
the main part of the body that I am having problems with:

<div id="MainMenu">
   <table border="0">
      <tr>
         <td id="Menu1" onmouseover="ShowLayer(1);">MainMenu 1</td>
         <td id="Menu2">MainMenu 2</td>
         <td id="Menu3">MainMenu 3</td>
      </tr>
   </table>
</div>

Within ShowLayer(n), I have an if clause to check for Netscape 4.X.  Then, 
within the if, I have a line that reads:
          MenuShow = "Menu" + n;
          alert(document.layers['MainMenu'].layers[MenuShow]);
However, when the alert pops up, all I get is "undefined".  If however, I 
change the alert to display document.layer['MainMenu'], I get "[object 
Layer]" for a value.

I would appreciate any and all help I can get.

Thank you,
Chris Cote
