Adding a preloader to determine external swf

Question

Hi there! I have a script which works wonders! but need to add a preloader to it so that a text box will show the % remaining?...
The code is randomising the files which is what I want but just need to add a preloader... any suggestions?
Sample:
filename = ["A01.swf", "A02.swf", "A03.swf"];
path = "A/";
i = filename.length;
k = Math.floor(Math.random()*i);
loadMovie(path+filename[k], movieTarget1);
Of if you know a link to something done before that would be swell!!!

Answer 1

filename = ["A01.swf", "A02.swf", "A03.swf"];
path = "A/";
i = filename.length;
k = Math.floor(Math.random()*i);
loadMovie(path+filename[k], movieTarget1);
clearInterval(preloadI);
var preloadI:Number=setInterval(preloadF,100);
function preloadF(){
var fl:Number=movieTarget1.getBytesLoaded()/movieTarget1.getBytesTotal();
if(fl>0){
yourtextfield.text = (100-Math.round(100*fl))+" % Remaining";
if(fl==1){
clearInterval(preloadI);
