    1) make an empty MC, for example called "alphaChange"
    2) write handler on this MC:

    onClipEvent (load) {
    start = 100
    end = 0
    speed = 1
    this.gotoAndStop(1)}
    }

    3)within this MC create three frames:
    //first frame only stops movie and adjusts a start value of targetMC alpha:
    targetMC._alpha = start
    this.stop()

    //second frame decreases aplha:
    targetMC._alpha = targetMC._alpha - speed

    //third frame decreases alpha and when alpha equals or
    //is more then end value, it stops

    if (targetMC._alpha < end) {
    targetMC._alpha = targetMC._alpha - speed
    this.gotoAndPlay (2}
    }else {
    this.gotoAndStop(1)
    }


    3) on button will be this script

    on (rollOut) {
    alphaChange.gotoAndPlay (2)
    }


    Just now you can change start and end values od alpha and speed of alpha changing. Or, if you want, you can set the speed value negative and you can call alphaChange MC to increase alpha....

    hope this helps

    Alex
