simple AS texttyping

[B_D]

Hi there!

Could someone help me with that basic script??
I don't know how to make it work correctly, like I wrote I would like to obtain
typing efect using only AS. That script is modified version of some typing efect using symbols & AS.

var i:Number = 0;
var h_space:Number = 10;
var x:Number = 30;
var texxt:String = new String("more rainy clouds");
//
_root.createEmptyMovieClip("letter_mc", i);
letter_mc.createTextField("letter_txt", i, 0, 0, 0, 0);
letter_mc.letter_txt.autoSize = "left";
//
_root.onEnterFrame = function() {
letter_mc.letter_txt.text = texxt.substr(i, 1);
letter_mc._x = i*h_space+x;
i++;
if (i == texxt.length) {
i = 0;
}

}; :confused:

end

Thanks in advance!!
