HUD/Movement Help

Im making a birdseye view game and to make a following camera i am moving the entire stage with something like this:

_level0._x -= (_root.guy._x+_root._x-140)/20;
    _level0._y -= (_root.guy._y+_root._y-140)/20;

it works fine…its all a peach.

cept i have no way of leaving things out…say…a HUD…
i cant think of a way to make it not pan with the stage…

is there anyway to leave certain movie clips out when moving the entire stage?
or is there a good way to make it move properly so those certain movie clips will stay in place?

please, any suggestions

thank you
