Clearing dynamic windows

[color=black][font=Arial]Hello, I am attempting to create a game for a business in flash and am looking for some counsel. I have a scoring system set up, and when you click in different areas the score is added to your total. Well I need a bankrupt button script that would clear your score (obviously) and a script to take the two scores that are displayed in their separate fields, and declare a winner. If you can please help on this it would be very beneficial.[/font][/color]
