Nested hitArea problem

[StateEgg]

Could someboby give me the right syntax for setting the hitArea of a graphic as follows:
Obj_A and Obj_B are nested inside Obj_C and Obj_D is on the main stage. I want Obj_C's hit test to be true when (only) Obj_A hits Obj_D.

I hope this is clear, I tried to simplify this as much as possible.
This is the line I am presently using but Obj_C's hit test is true when either Obj_A or Obj_B hit Obj_D.

_root[Obj_C[i]].hitArea=_root[Obj_C[i]]+"."+[Obj_A[i]];

Thanks

Hi
This example has two clips(Obj_a,Obj_b) inside Obj_c clip on the main stage.
Obj_d is a single clip also on main stage.

code:

---

Obj_c.onEnterFrame = function() {

	if (this.Obj_a.hitTest(Obj_d)) {

		trace("hitting");

	}

};

Thanks, this worked perfectly.
