flash actionscript: HI

The problem is that I cannot get the value from class and then used it in
textfield.

I'm getting different values from XML file and one of them is name of current
song.

It works fine when I trace it inside of for loop which is inside xml.onLoad
function
but when I want to trace it outside of that xml.onLoad function it traces me
undefined and the same result is in any other function...

I don't know where is the problem. I'm sure it's my fault because this is my
first class and I don't know much of it right now.

If you have any idea what am I doing wrong please tell me.

Thanks in advance

This is the current code of that class:

Thanks for reply!

Here is XML file:

<?xml version="1.0" encoding="iso-8859-1"?>
<soundPlayer>
<song
_band_txt="Janis Joplin"
_song_txt="Piece of My Heart"
_album_txt="Album"
_src="Janis_Joplin_-_Piece_of_My_Heart.mp3"
/>
<song
_band_txt="Billy Idol"
_song_txt="Sweet Sixteen"
_album_txt="Album"
_src="Billy Idol - Sweet Sixteen.mp3"
/>
</soundPlayer>

Sample code for using it:

import com.mloncaric.*;
//
var sound:soundPlayer = new soundPlayer();
//
sound.loadXML("soundPlayer.xml");
//
play_btn.onRelease = function() {
sound.playSong();
};

Put a trace on _index in the progressStatus() function:
function progressStatus(pBar:MovieClip, scrub_mc:MovieClip, posBar:MovieClip,
ozadje_mc:MovieClip) {
_loaded = _sound.getBytesLoaded()/_sound.getBytesTotal();
pBar._width = _loaded*ozadje_mc._width;
scrub_mc._x = (_sound.position/_sound.duration)*pBar._width;
posBar._width = scrub_mc._x;
trace(_index);
}
What's the result?

I get undefined... I've tried that before and many other variables...but all
what I get is undefined, exept in playSong function loadSound works fine...
This is my first class so it's big possibility that the problem is in bad
formed class, and because of that I don't know much about scopes and similar
things...

Thanks for reply

Well, I can't run the complete code (just the xml part) but it looks like a
scope problem. I can't see from what scope the function progressStatus is
running. Try using the local reference to the class (similar to the usage in
loadXML) --- var root=this; and try calling class members using that reference.
Otherwise you can zip ALL files and post a link to the zip so I can run the
code here.

Thanks for helping me!

Here is link to files(without of mp3s for keeping the small size of rar file)

OK, here is zip file:

See attached code - lines 24/25 and 167/168

XML file is the same...

This code will be updated soon, but for now it works fine:D

Thank you very much man for all your time you wasted for me, and help.
