"Error opening URL 'http://url.com' " to text field

1

Good Morning/Afternoon/Evening

I’ve constructed an mp3 player like swf to later go into a project I am working on.
This mp3 player like swf has two input text field:
one to type in a directory path
one to type in an mp3 file
Then you push “Get MP3” button and it plays the MP3.
It of course has a pause, play, volume slider, balance slider and your primary id3 tags. Looks great, works great but…

I would like Flash to make an MC visible with a text field that says "Error opening URL ‘http://url.com’ " to text field. I just have no clue how to capture the “Error Opening URL” and if I can capture the "Error opening URL “file:///D:\music\ est.mp3” I would like to omit the “file:///” part of the error message as well.

For realz though… it doesn’t even have to do all that it could just say with static text “File not found. Please try again.”

Um… I should be able to script my own MC._visible/!_visible just don’t know how to check for file not found.

I appreciate any and all attention provided.
Crux

P.S. Here is my Frame 1 script in case it helps. Only other scripts are volume and balance and they don’t pertain to help request.

//Load Song to new Soundvar song_sound:Sound = new Sound();
song_sound.setVolume(100);
this.onEnterFrame = checkSound; 
song_sound.onLoad = function() {
    song_sound.start();
};

//Song duration function
function checkSound() {
    var percent:Number = Math.round((song_sound.position/song_sound.duration)*100);
    if (percent <100) {
        tSongDur.text = percent+"%";
    } else {
        tSongDur.text = "Play MP3";
    }
}

//import ID3 tags
song_sound.onID3 = function():Void  {
    tArtist.text += "Artist: "+song_sound.id3.artist+"
";
    tSong.text += "Song: "+song_sound.id3.songname+"
";
    tAlbum.text += "Album: "+song_sound.id3.album+"
";
    tTrack.text += "Track: "+song_sound.id3.track+"
";
    tYear.text += "Year: "+song_sound.id3.year+"
";
    tComment.text += "Comment: "+song_sound.id3.comment+"
";
};

//Play and Pause Functions
function pauseSong():Void {
    pos = song_sound.position;
    song_sound.stop();
}
function unpauseSong():Void {
    pos = song_sound.position;
    song_sound.stop();
    song_sound.start((pos/1000));
}

//Buttons
btnPauseSong.onRelease = pauseSong;

btnUnPauseSong.onRelease = unpauseSong;

btnGetMP3.onRelease = function() {
    song_sound.loadSound(tDir.text+tGetMP3.text);    
};
