Drop target

I have created a magnifying glass effect, by using a target as a magnifying glass image and a set of objects. I used the kirupa tutorial as a base
http://www.kirupa.com/developer/actionscript/dragdrop.htm
However I want to have multiple objects changing on drag and drop.
Is this possible. Do I just need something like an if…else code to be inserted after the stopDrag command in the kirupa code above or is there another way?
