MovieClipLoader with multiple movies

I’m using the MovieClipLoader () class to load 1 swf and 1 jpg, what I want is that once BOTH are loaded a certain command get executed.

Right now the command get executed twice, since it does it once the swf is loaded, and once the jpg is loaded:

[AS]
var pagecontent = new MovieClipLoader();
pagecontent.loadClip(page + “.jpg”, _root.mc_foto.mc_fposition);
pagecontent.loadClip(page + “.swf”,_root.mc_cposition);

//CONTENT PRELOADER
pagecontent.onLoadProgress = function (targetMC, loadedBytes, totalBytes) {
_root.mc_ploader._visible = true;
}
pagecontent.onLoadInit = function (targetMC) {
_root.mc_articles.easeXf (701);
_root.mc_ploader._visible = false;
_root.mc_cposition._visible = false;
}
[/AS]
