Trouble with deleting a child from main camera.

Hey everyone, I'll try to make this short and sweet. I have this astronaut player, asteroids, and asteroid indicators (flashing arrows that show where an asteroid is approaching from). Every time an asteroid is spawned, an asteroid indicator is spawned as a child of the main camera (so that the indicators move with the player). I have an Asteroid script attached to every asteroid, which checks the distance between itself and the player. When an asteroid comes within a certain distance of the player, I try to delete the first child of the main camera (because the "oldest" child would correlate with the closest asteroid to the player). As of now though, the child on the camera doesn't delete when an asteroid comes within range of the player, any ideas or help is appreciated!
