Vertical Navigation flyout 5 deep CSS

I have a nightmare of a client that wants this indepth idiotic navigation system on his website... it is basically this web of mouse overs and nested tables.. I found something that I like but cannot seem to get it to function past the first tier:

the issue is that once the user mouses over the first visible object, every sub table shows up as opposed to the first level, then the next, then the next and so on and so forth....

I like this script for the small size and easy to understand concept in case he wants to */shudder/* augment the table himself....

Any help would be greatly appreciated.

 

could you post your code, its probably as simple as you set the a:hover incorrectly
