Few codes: movie and sound

Hello

I have few challenges before me, but actionscripting is not my strong side.

I use Flash MX 6.0

  1. I have a button and when I put cursor over it, it must start looping a sound. When I drag away, the sound must stop. I would be even cooler if it was possible to make the sound fade away when the mouse is rolled away. I have no problem creating another sound file that fades my current sound away.

  2. I have a button which represents a knife, that should stab something (a panel) once pressed. So fist the knife must be clean. but after one or more presses, the blood should remain as a movie clip (as I want to animate the dripping blood)

  3. once rolled over a button, the sound must start looping (as I wrote in 1.) AND the knife should slowly go backwards (MC). BUT when I roll mouse away, the sound fades away (as in 1. again) PLUS the knife should slowly move back to its place in stead of just jump from one place to another.

I would appreciate any help alot!

Thanks in advance
