Transition betwen external SWFs

Hello ,

I try to create a transition betwen external SWF , but I cant’t succeed .
I followed the tutorial :
http://www.kirupa.com/developer/mx2004/transitions2.htm

I created the buttons , the mouvie clip…
I have put the SWF in the library .

Could it be the reason of my failure ? Where the SWF should be ? Or there is maybe another explantation ?

Many thanks :beer:
