Reference a dynamic movieclip from an outside movieclip

Hey everybody
i have created a movieclip (parentMC) that houses two movieclips within it (childA and childB)

in childA, i am dynamically creating movieclips via a loop:


var newX = 0;
var pagTotal = 8;

for(i=1; i<pagTotal+1; i++){
    var pagMC:MovieClip = this.attachMovie('btnPag0'+i, 'pagClip0'+i, this.getNextHighestDepth());    
    
    var pagMC_w = pagMC._width;
    var total_w = pagMC_w * pagTotal - pagMC_w;
    
    pagMC._x = newX - total_w/2;
    pagMC._y = 5;
} 

…and in childB i’m trying to reference one of these created movieclips via “_parent.childA.pagClip01” so on and so forth.

but they dont seem to be working. when i trace the dynamic clip from within childB i keep getting “undefined” in the output. however, I can reference the movieclip from within childA, and even from parentMC no problem.

i’ve used _root and _level0 absolute paths and still the same failed result. any help is appreciated!
