Hi, experts

I have the following code that import external images. First, it will display small images and user can see zoom in images when click on small images..... The problem is when click on small image that zoom in image is not showing up [ function buttonClick() ]. Please any suggestion welcome. Thanks

Code

var _loc1 = this;
//
function loadMe() {
      myX = 62;

      counter = 0;
      var ScrollMovie:MovieClip = _loc1.createEmptyMovieClip("ScrollMovie", 1);
      for (n=1; n<howMany; n++) {
            mc = ScrollMovie.createEmptyMovieClip("myTarget"+n, 20+n);
            picture = "netblue/"+projects[n]+".jpg";
            eval("ScrollMovie.myTarget"+n).loadMovie(picture);
            //mcLoader.loadClip(picture, eval("ScrollMovie.myTarget"+n));
