I m trying to loop through MovieClips

Here s the code



theArrayPics =new Array();
theArrayPics.push("pic1","pic2","pic3","pic4,"pic5");

var num:Number=4;
var ok:Boolean=false;

var the_dude= setInterval(doTheJob,2000);

function doTheJob()
{
if(ok)
{
_root[theArrayPics[num+1]].removeMovieClip();
//I m wondering why this actually doesent work?
trace("Get lost dude!");

}
else

ok=true;    
_root.attachMovie(theArrayPics[broj],theName+"num",_root.getNextHighestDepth());
trace(num);
num-=1;

}
