I tried adding the combo box component to my mp3 player but ran into a little problem. When i choose an option from my combo list it just counts +1 in my song array. I figured the problem was in my playSong function but I tried changing some of that code around and it didn’t seem to help matters. Anyone got any tips or answers I’d love to hear them.

**songs.xml**

\<?xml version=“1.0” encoding=“iso-8859-1”?\>

\</songs\>

**Song.as**

class Song{  
public var earl:String;  
public var artist:String;  
public var track:String;  
public var uime:Number;

```
public function Song(e:String, a:String, t:String, u:Number){
    earl = e;
    artist = a;
    track = t;
    uime = u;
}

```
