ActionScript 2.0 :: Attaching MovieClip And Assigning It Coordinates Of Another Movie Clip

I'm making a game where an airplane loads using attachMovie, with a randomly assigned y coordinate and a constant x. The airplane then moves across the screen. You hit another button, and a parachutist is loaded using attachMovie, with the coordinates being set equal to the current coordinates of the airplane. The parachutist loads but he doesn't load to the coordinates of the airplane. If I feed the parachutist numerical coordinates, he loads to those coordinates, but for some reason Flash seems to be completely ignoring my attempts to feed the plane's coordinates to the parachutist. Here's the relevant code, which is of course nested in an onEnterFrame function:

if (Key.isDown(Key.DELETEKEY)){
if (jumped == false){
attachMovie("jumperWhole", "jumper", 0);

[Code].....

As I've said, the jumper loads, he just loads in the upper corner of the game, as if the plane's coordinates are ignored and Flash attaches jumper to the default coordinates of the program. If I try to attach the jumper to the using the coordinates of something that's not in motion, it works, so I'm wondering if this has something to do with the motion of the plane.
