Errors in Action Script 3 in streaming .mp3 player - actionscript

Question

I'm trying to build a streaming .mp3 player to run various sound files on my web site. To do that, I followed a tutorial that includes a code template at:
http://blog.0tutor.com/post.aspx?id=202&title=Mp3%20player%20with%20volume%20slider%20using%20Actionscript%203
However, whether I preserve the template's direction to the author's own sound file or insert my own direction to my online sound file, I keep on running into glitches in the ActionScript that I can't fathom.
Those errors are:
1084: Syntax error: expecting rightparen before _.
1086: Syntax error: expecting semicolon before rightparen.
When I try to correct them, I get new errors. I can't determine whether the sound file is loading; it certainly never plays. The volume slider does not work.
I did find one line that looked like it should have been commented out, the one that reads
to start at the same place
So I tried commenting that out. No dice. Same errors.
Thanks in advance for any suggestions. Code follows:
var musicPiece:Sound = new Sound(new URLRequest _
("http://blog.0tutor.com/JeffWofford_Trouble.mp3"));
var mySoundChannel:SoundChannel;
var isPlaying:Boolean = false;
to start at the same place
var pos:Number = 0;
play_btn.addEventListener(MouseEvent.CLICK, play_);
function play_(event:Event):void {
if (!isPlaying) {
mySoundChannel = musicPiece.play(pos);
isPlaying = true;
}
}
pause_btn.addEventListener(MouseEvent.CLICK, pause_);
function pause_(event:Event):void {
if (isPlaying) {
pos = mySoundChannel.position;
mySoundChannel.stop();
isPlaying = false;
}
}
stop_btn.addEventListener(MouseEvent.CLICK, stop_);
function stop_(event:Event):void {
if (mySoundChannel != null) {
mySoundChannel.stop();
pos = 0;
isPlaying = false;
}
}
var rectangle:Rectangle = new Rectangle(0,0,100,0);
var dragging:Boolean = false;
volume_mc.mySlider_mc.addEventListener(MouseEvent.MOUSE_DOWN, startDragging);
function startDragging(event:Event):void {
volume_mc.mySlider_mc.startDrag(false,rectangle);
dragging = true;
volume_mc.mySlider_mc.addEventListener(Event.ENTER_FRAME, adjustVolume);
}
function adjustVolume(event:Event):void {
var myVol:Number = volume_mc.mySlider_mc.x / 100;
var mySoundTransform:SoundTransform = new SoundTransform(myVol);
if (mySoundChannel != null) {
mySoundChannel.soundTransform = mySoundTransform;
}
}
stage.addEventListener(MouseEvent.MOUSE_UP, stopDragging);
function stopDragging(event:Event):void {
if (dragging) {
dragging = false;
volume_mc.mySlider_mc.stopDrag();
}
}

Syntax errors are just what it says they are, the code is not properly written. For instance , you shouldn't have an underscore after URLREquest
var musicPiece:Sound =
new Sound(new URLRequest("http://blog.0tutor.com/JeffWofford_Trouble.mp3"));
to start at the same place should be commented out, simply because it's a comment, it's not a variable or a function.
to call a function "play_" is not really good practice either. Call it soundPlay, if you're concern about conflicts.
same comment for pause_ and stop_
