Character Customization in Flash

I apologize if this is a repeated question. I searched around, and learned a bit, but I couldn’t find all the information I need.

I’m creating a character customization screen for my RPG. I understand how to addChild for each different article of clothing/hairstyle/etc., however I don’t understand how to write the script telling the game which hairstyle to use. Like, if I pick a bald hairstyle, how do I tell the game to use that hairstyle rather than another?
