Mouse Trail

I am trying to get the code to work for the mousetrail animation. I wanted to change the color and the word. Somehow, when i play the movie, the initial instance displays the word at first and then reverts back to ‘kirupa’ and the color doesnt change. Can anyone help me with that? PLEASE? I really need it quite urgently, and havent been able to figure it out. TIA!

CODE below:

Text = “Kirupa has the best site on the net!!!”;
letters = Text.split("");
letterformat = new TextFormat();
letterformat.font = “Verdana”;
letterformat.align = “center”;
letterformat.size = “10”;
spacing = 8;
speed = 3;
for (var LTR = 0; LTR<letters.length; LTR++) {
mc = _root.createEmptyMovieClip(LTR+“l”, LTR);
mc.createTextField(letters[LTR]+“t”, LTR, LTR*spacing, 10, 20, 20);
with (mc[letters[LTR]+“t”]) {
text = letters[LTR];
setTextFormat(letterformat);
selectable = false;
}
if (LTR) {
mc.prevClip = _root[(LTR-1)+“l”];
mc.onEnterFrame = function() {
this._x += (this.prevClip._x-this._x+5)/speed;
this._y += (this.prevClip._y-this._y)/speed;
};
} else {
mc.onEnterFrame = function() {
this._x += (_root._xmouse-this._x+10)/speed;
this._y += (_root._ymouse-this._y)/speed;
};
}
}
