Hey there!

I’m working on a little ‘scaler function’, and I’m almost done! 😉  
But I would to add some elasticity to the movement, but I’m not quite sure on how to apply it… Not that good at actionscripting… yet! 🙂  
Kinda make it bounce instead of just ‘easing’…!?

I hope you understand what I’m saying!? - any help would be nice! (see attached .fla)

Thanks for replying david! But I’ve been through that tutorial, and still I can’t find out on how to apply the effect to my ‘scaling’…! ☹
