Change Stacking Order (swapDepths)

Hi, I was reading an old article about swapDepths and was wondering if you could explain how you’d increase a second panel relative to the panel being dragged.

[SIZE=2]If I want another panel to increase its stacking order in relation to this panel, I can blindly increase the stacking position of that panel, or, I can increase a variable stored on the main timeline by a certain value so all movie clips are in sync.[/SIZE]

To describe my project, I have 4 nav movieclips that I want to swap depths on rollover and also bring a movieclip of a opacity fade-in up to one depth below the mc the mouse is over.

So basically I’m looking for this when I rollover MC1:

Any help would be sweet. Thanks.
