Need to 'eval' num. use array notation.

controller_mc.attachMovie("gallery_mc", "gallery_mc", 50);
theGallery = controller_mc.gallery_mc;
gallery_contains = 4;

for (i = 0; i<gallery_contains; i++){
    num = "img_"+i;
    theGallery[num]._alpha  = 0;
    trace(num);
}

Subject: [Flashcoders] String problems?

I am writing this wrong:


controller_mc.attachMovie("gallery_mc", "gallery_mc", 50);
theGallery = controller_mc.gallery_mc;
gallery_contains = 4;

for (i = 0; i<gallery_contains; i++){
    num = "img_"+i;
    theGallery.num._alpha  = 0;
    trace(num);
}

gallery_mc has _mc's in it named, img_0, img_1, img_2, img_3.

What am I doing wrong here?
