problemas con loadMovie

[venommdt]

function preload() {
MC_imagen1.loadMovie("foto1.jpg");
MC_imagen2.loadMovie("foto1.jpg");
MC_imagen3.loadMovie("foto1.jpg");
MC_imagen4.loadMovie("foto1.jpg");
this.onEnterFrame = function() {
this.I_Perc = (MC_imagen1.getBytesLoaded()/MC_imagen1.getBytesTotal())*100;
this.I_Perc2 = (MC_imagen2.getBytesLoaded()/MC_imagen2.getBytesTotal())*100;
this.I_Perc3 = (MC_imagen3.getBytesLoaded()/MC_imagen3.getBytesTotal())*100;
this.I_Perc4 = (MC_imagen4.getBytesLoaded()/MC_imagen4.getBytesTotal())*100;

zz = Math.round(this.I_Perc);
zz2 = Math.round(this.I_Perc2);
zz3 = Math.round(this.I_Perc3);
zz4 = Math.round(this.I_Perc4);
if(zz<=99 || zz2<=99 || zz3<=99 || zz4<=99){
MC_Loader.TF_Percent.text = Math.round((zz + zz2 + zz3 + zz4) / 4);
}
if(this.I_Perc == 100 && this.I_Perc2 == 100 && this.I_Perc3 == 100 && this.I_Perc4 == 100) {
delete this.onEnterFrame;
gotoAndStop(2); //Comenzar la pelicula
} else {
this.stop();
}
}
}

Utilizalo para los cuatro movieClips, reemplazando por cada uno en:

if(zz<=99){
MC_Loader.TF_Percent.text = zz2;
}
if(this.I_Perc == 100) {
delete this.onEnterFrame;
gotoAndStop(2); //Comenzar la pelicula
} else {
this.stop();
}
