Scrolling Flash Text

how do you make text scroll if it is longer than the block it is in

[jrthib]

I have an mp3 player on my website that plays songs and takes the descriptions from an xml file. If the song name/artist is too long for the block that it is in it only displays what will fit. How would i make it so the text would scroll if it is too long so it would display the whole line? Here is my action script

stop();
playlist = new XML();
playlist.ignoreWhite = true;
playlist.onLoad = function(success) {
if (success) {
_global.songname = [];
_global.songband = [];
_global.songfile = [];
for (var i = 0; i<playlist.firstChild.childNodes.length; i++) {
_global.songname[i] = playlist.firstChild.childNodes[i].attributes.name;
_global.songfile[i] = playlist.firstChild.childNodes[i].attributes.file;
trace(songname[i]+" "+songfile[i]);
}
}
_root.createEmptyMovieClip("sound_mc", 1);
_root.sound_mc.sound_obj = new Sound();
_global.song_nr = random(songfile.length);
_root.sound_mc.songStarter(songfile[song_nr], songname[song_nr]);
};
MovieClip.prototype.songStarter = function(file, name) {
this.sound_obj.loadSound(file, true);
this.onEnterFrame = function() {
if (this.sound_obj.position>0) {
delete this.onEnterFrame;
this._parent.display_txt.text = name;
} else {
this._parent.display_txt.text = "loading...";
}
};
this.sound_obj.onSoundComplete = function() {
(song_nr == songfiles.length-1)? _global.song_nr=0 : _global.song_nr++;
_root.sound_mc.songStarter(songfiles[song_nr], songname[song_nr]);
};
};
btn_play.onRelease = function() {
this._parent.sound_mc.songStarter(songfile[song_nr], songname[song_nr]);
};
btn_stop.onRelease = function() {
this._parent.sound_mc.sound_obj.stop();
};
btn_fw.onRelease = function() {
(song_nr == songfile.length-1)? _global.song_nr=0 : _global.song_nr++;
_root.sound_mc.songStarter(songfile[song_nr], songname[song_nr]);
};
btn_rev.onRelease = function() {
(song_nr == 0)? _global.song_nr=songfile.length-1 : _global.song_nr--;
_root.sound_mc.songStarter(songfile[song_nr], songname[song_nr]);
};
playlist.load("playlist.xml");
