Please... I need your help!!!!

Hello friends, I need your help.

I have assembled the following code, I honestly do not know much about flash and developing the person who has disappeared and left alone.

Need to know how to insert the volume control for this player and set a default value.

I ask all who can lend a hand to solve this problem.

Thanks to all!

//Declaracion de variables
var duracion:Number=10000000000000;

var flv:String='../../../'+unescape(_root.flvFile);

//trace(flv);
//var flv='video.flv';
//aviso.text=flv;

//trace(flv);
var conexion:NetConnection = new NetConnection();
conexion.connect(null);
var stream:NetStream = new NetStream(conexion);
video.attachVideo(stream);
stream.setBufferTime(10);
stream.play(flv);
//stream.pause();

//Precarga para el archivo FLV
this.onEnterFrame=function(){
//obtengo el porcentaje
var valor1:Number = Math.round(stream.bytesLoaded/stream.bytesTotal*100);
estado.text=valor1;
//basandome en el porcentaje modifico la barra
barra_mc._xscale = valor1;
//si completa el porcentaje mayor a 100
//elimino el onEnterframe
//porque ya cargo el FLV
if (valor1>=100) {
    delete this.onEnterFrame;
}
