How to make this keep character packages? [UNSOLVED]

For some reason, this script I made doesn't keep the character packages. It has the default ROBLOX 1.0 body parts, and I want it to load any body package the player might be using. It's a First Person Body script, by the way. Currently, I have it set to only render the legs in first person.
