[FMX2004] hide MC?

Hello,

I’m having hard times hiding dynamicly created MC…

[AS]
for (i = 0; i < mycounter; i++){
_root.createEmptyMovieClip(“photoholder”, 3000+i);
_root[“photoholder”+i].loadMovie(photourl+i);
_root[“photoholder”+i]._visible = false;
}
[/AS]

They load just fine but i can’t hide em on the fly, why?
