Help with DIV layer menu position when centered

[imanta]

I have a menu/submenu combo that uses DIV layers, JS, and CSS that workd great currently. The problem I have is that it was designed in a way where everything is absolute. Code looks like this:

<div id="platform_menu" style="position:absolute; left:10px; top:82; width:108; height:17; z-index:3; visibility: visible;">
Content
</div>

Then when the person mouseovers the content in the first div it triggers a sub layer which appears at the time same position:

<div id="platform_submenu" style="position:absolute; left:10px; top:99; width:108; height:108; z-index:21; visibility: hidden;"> 
Submenu
</div>

The question is, how do I make this so it can be centered on a screen? Keep in mind I have multiple _menus and submenus so each submeny would have to know the location of their parent.

Thanks for the help!
