Targeting dynamically generated MCs

1

I have some movieclips…Which i want to make on release actions for;
MCs Made as follows…

for(i=0; i<allNews.length; i++){
        
        duplicateMovieClip(_root.newsBox.newsCount.allNumbers.newsNumber, "newsNumber"+(i+1), 5+i);
        _root.newsBox.newsCount.allNumbers["newsNumber"+(i+1)].digit = (i+1);
        _root.newsBox.newsCount.allNumbers["newsNumber"+(i+1)]._x = (numberX+(numberW*(i+1)));
        }

I cant seem to target them!
What am i doing wrong?

I have the following on the M-clip that is being duplicated, but i feel i need to generate this somehow after the clips are duplicated on stage in order for this to work…

on (release){
    //function clickedNews(){
    _root.newsBox.newsContent.title = allheadings[(this.digit)];
    _root.newsBox.newsContent.content = allNews[(this.digit)].firstChild;
    _root.newsBox.newspicbox_mc.loadMovie("content/newsthumb"+[this.digit]+".jpg");

Many Thanks for any help people… in advance.
