Flash Banner rotator

You can make a flash file, and so from your site make a variable there tells which images/flash file it should load.
In this flash file can you so revice them variable and load the image/flash file into it.

Hope you understand, and you need help to make it, or just the way to make it?

I need a little help to actually make it work. I have made a file that get FlashVars. I am sending vars as such.

file1=ext1.swf&file2=ext2.swf&file3=ext3.swf

Now what I have to do is get them to rotate in flash plus if as to start in a random order and that is where I am lost.

I cooked up something... at least what I think it would do. It would be great if one of you could check it for me and perhaps optimize it a little. Plus is it possible to fade a new file in and out? If so can you help? Thanks again :)

var curcount:Number = Math.floor(Math.random() * (3 - 1) + 1);;
var maxcount:Number = 3;

files = new Array(file1,file2,file3);
delay = new Array(time1,time2,time3);

movieloader(files[curcount]);

var si:Number = setInterval(function ()
{
    if(curcount == maxcount){
        curcount = 0;
    }

    movieloader(files[curcount]);
   
    (curcount >= maxcount) ? clearInterval(si) : curcount++;

}, delay[curcount]);



function movieloader(file){
    trace (file);
   
    var myLoader:MovieClipLoader = new MovieClipLoader();
    myLoader.loadClip(file, myContainer);
}
