(CS5 - AS3) Play MC on AddChild

Hello,

I’m making a Flash site. Right now I’m trying to add a MovieClip from the library to the stage via AS3, and have the MovieClip play its frame one. At the end of this MovieClip I have a stop();. When I click on the button, the MovieClip has already played through.

Sorry for the noob question, and thanks for any help!
