Hi,

I am trying to write an mp3 player. I have tried everything and am suck getting the duration of an mp3.

Heres my working code:

```auto

on(press){
	
	function callback1() {
trace("mySound completed");
i++;
output_txt=my_lv2["out"+i];
my_lv["parent"].my_sound.loadSound(my_lv["var"+i],true);
	}
my_sound.onSoundComplete = callback1;

var my_sound:Sound = new Sound();
var my_lv:LoadVars = new LoadVars();
my_lv["parent"] = this;
my_lv.onLoad = function(success:Boolean) {
if (success) {
	
my_lv["parent"].my_sound.loadSound(my_lv["var"+i],true);
my_sound.onSoundComplete = callback1;
} else {
trace("Error loading/parsing LoadVars.");
}
};
my_lv.load("playText.txt");
	
var my_lv2:LoadVars = new LoadVars();
my_lv2["parent"] = this;
my_lv2.onLoad = function(success:Boolean) {
if (success) {
output_txt=my_lv2["out"+i];
} else {
trace("Error loading/parsing LoadVars.");
}
};
my_lv2.load("outputFile.txt"); 
	
}

```

can anyone help me finish this code to print the total time of a track?

Regards  
Aubrey.
