Problems with a menu

Hello everyone, I am new to flash and although i have so far been able to self teach myself, I am finally stuck. Here is the problem I am having:

I am creating a simple infinite scrolling image gallery. When one of the scrolling images is clicked, a larger version of that specific image will be loaded into a empty movieclip. I understand how to load the image into the empty movieclip, but I cannot figure out how to correctly reference the images within the scrolling gallery.

Perhaps someone could take a look at my file and help me out? I apologize if a similar question has been asked previously, I have looked through past threads for the last hour and have not turned up anything useful. Below is a link to my FLA file.

Thank you so much!
