Music control slider bar as2

OK I have been following a tutorial and making modifications as I went to make it work with what i needed. Now the only problew is I cant get it to play my linked song right and the slider I am using wont stopDrag lol.
here is my code.


onClipEvent(enterFrame)
{
_root.mslider.slider.onPress = function(){
    _root.mslider.slider.startDrag(true, _root.mslider.bar._x, _root.mslider.bar._y, _root.mslider.bar._x + 200, _root.mslider.bar._y);
}
    _root.mslider.slider.onRelease = function() {
        _root.mslider.slider.stopDrag;
}
    _root.playbutton.onRelease = function() {
        Mysong = new Sound();
        Mysong.attachSound("battletheme");
        Mysong.start(0, 10);
}
    _root.stop_btn.onRelease = function() {
        stopAllSounds;
}
_root.mslider.slider.onMouseMove = function(){
    newPoint = new Object();
    newPoint.x = _root.mslider.slider._x;
    newPoint.y = _root.mslider.slider._y;
    _root.mslider.bar.globalToLocal(newPoint);
    _root.Mysong.setVolume(-1*newpoint.x);
}
}

Can someone please help me fix it?
