Sliding volume controller for main timeline.

Question

I am trying to change the volume on my sound files which are located on the main timeline.(sync = streaming)
I can use a allSound.setVolume(#) to control the sound level across the timeline.
But when trying to use a sliding volume control, I get confused.
This is the code I used for the sliding volume controller
this.ratio = 0;
dragger.onPress = function() {
    this.startDrag(true, 0, 0, line._width, 0);
    this.onEnterFrame = function() {
        ratio = Math.round(this._x*100/line._width);
        _root.volume = ratio;
dragger.onRelease = dragger.onreleaseOutside=stopDrag
I started using this code for the volume control but haven't had any success with it yet.
dragger.onPress = function() {
    StartDrag(3);
If you have any suggestions or clues for where I could find a tutorial that would be great.
Thanks,
t.a.s.n.

Answer 1

I'll offer this solution which I utilized some time ago (I don't often deal with sound, and I normally avoid postings concerning it in the forums).
My sliding volume control is basically a two frame movieclip (volume_mc) which contains a volumeBtn object where the first frame code is:
volumeBtn.onPress = function(){
startDrag(volumeBtn, false,0,0,100,0);
gotoAndStop(2);
volumeBtn.onRelease = volumeBtn.onReleaseOutside = volumeBtn.onRollOut =function(){
stopDrag();
gotoAndStop(1);
In frame 2 the code is:
stop();
this.onEnterFrame = function(){
_parent.adjustVolume();
In the parent timeline, the adjustVolume function is as follows:
function adjustVolume(){
currentVolume = volume_mc.volumeBtn._x;
s.setVolume(currentVolume);
I use the "_x" value mainly because my sliding length is 100 pixels, starting a 0 for the volumeBtn position.  But you should be able to utilize the percentage method you have to acquire a similar result.  The currentVolume variable is declared/assigned intially elsewhere in the parent code.
