Action Script 2 to 3 Migration. HELP!

[FONT=Arial]I have a function that I am trying to migrate from action script 2.0 to 3.0. If someone could give me some help/guidance on where to begin that would be great! I’m stuck and I don’t want to be held up on this forever.[/FONT]
[FONT=Arial]Thank you![/FONT]
