Duplicating Multiple MC's

programming flash
1

Hello. I have 5 movie clips that I am trying to duplicate.

I was going well but then i decided to make it so they appear at certain intervals using the amount of seconds elapsed.

now only MC2 is duplicated.

Any ideas what I need to do?


var PreElapsedS=0;

dupCir = function(mc:MovieClip, interval:Number){
    mc.onEnterFrame = function(){
        if(elapsedS==PreElapsedS+interval){
            mc.duplicateMovieClip (mc+elapsedS, _root.getNextHighestDepth());
            PreElapsedS=elapsedS;
        }
    }
}

dupCir(MC1, 60);
dupCir(MC2, 5);
dupCir(MC3, 30);
dupCir(MC4, 25);
dupCir(MC5, 10);

Thanks
