Seek and volume bar problems for mp3 player

Hi,

I am trying to make a mp3 player which uses a xml file for the songs in flash 8.
I got some free code from different places and I have modified it to make some of the functionalities work but I am still struggling with a few more…

The first one is a scrubber, which can be dragged to seek different positions in the song.
I have a scrubber_mc, which is like a background to the progress bar. That let’s me seek different positions in the song if I ‘click’, but what I need is a scrubber that can appear like a small arrow that can be ‘dragged’ to different positions in the song.

I have written some code but don’t understand why it is not working… the scrubber is called playhead_btn which is inside a movieclip called seekbar_mc which also has the progessbar_mc which shows the progress of the song.

seekbar_mc.playhead_btn.onPress = function() {
seekbar_mc.playhead_btn._x = seekbar_mc.progressbar_mc._width + seekbar_mc.progressbar_mc._x;
var leftLimit = seekbar_mc.progressbar_mc._x;
var rightLimit = seekbar_mc.progressbar_mc._width + seekbar_mc.progressbar_mc._x;
this.startDrag(“seekbar_mc.playhead_btn”, false, leftLimit, seekbar_mc.progressbar_mc._y, rightLimit, seekbar_mc.progressbar_mc._y);
}

seekbar_mc.playhead_btn.onRelease = function() {
this.stopDrag();
}

seekbar_mc.playhead_btn.releaseOutside = function() {
this.stopDrag();
}

Another functionality that I am trying to get working is a volume control. I have a line of code on the main timeline of the player:

this._sound.setVolume(song_volume);

and I have the rest of the code in the volume_mc movieclip. I am being able to increment and decrement the counter on the volume control but it is not affecting the actual volume of the song being played. I am not sure what I am missing.

I am not very good at actionscript but try to read up stuff and try it out. To help you help me, I am attaching a copy of the .fla file. I really hope someone can help me.

Thank you in advance.
