Swapdepth and movieclip(s)

I’m using the tutorial on this site called ‘swapwindow_final.fla’
I’ts very skilful.

I have a question about using Swapdepth.
When i’m using this the normal way it’s working. No problem.
Question/Problem:
When i make one movieclip of this all together, it won’t work anymore.
Still drag and drop work, but Swapdepth???

Who can help me on my way.
