Why is a new movieClip not being created?

programming flash

Hey there, this should be a pretty simple one. I am trying to dynamically generate a movie clip, attach a movie clip from the library and then animate a tween but for some reason, even though the name is being generated dynamically to be different every time and each new MC is put on a different depth, the first movie clip disappears once a new one is generated.
if someone could help me figure this out I would be very grateful!
Here’s my code:
