Shared RunTime Library

I have a compiled movie BTBRBand.swf that imports two shared swf’s ( a blank T-Shirt swf and image of a rock band swf). This runs fine. Problem is when I try to transfer BTBRBand.swf into the library of a new .FLA of a page intended to display BTBRBand.swf nothing happens.

What I am trying to do is display in an online shop, multiple different coloured T-shirts that use the same image.
Am I trying to do the impossible?
