Flash Help pleases.

Hey-oh, and thanks in advance for any help anyone can offer.

I have a fun filled question about flash, I'm working on a website which I'm programming dynamically, and I am loading thumbnails to a sliding scroll bar which moves up and down. This much works. What I need to happen is have the ability to click one of these thumbs, and have the relative picture go up. It is not working. If I don't load the image to the holder then it works, but that makes things difficult.

Heres all of the code I believe to be relevant, I would really appreciate any help. Thanks.

scrollbar_mc["thumbHolder"+m].loadMovie(thumbImageHolder[m]); // loads thumb image to appropriate thumb HOLDER

imageToScreen(imageFolder,inputNum,Number(this._name.substr(-1,1)));
}

So, if I don't load the image to the holder, then I can click the holder and it will load the image. This tells me its because my code is referring to clicking the holder instead of the image... but I've tried all kinds of ways to refer to the loaded image so that they can click that and they haven't worked. Thanks for any help you can offer.
