Createmovieclip problem?

hi.

Im having problems with a photogallery im doing. I create a MC with createMovieClip, to load the main pics into.I also have a movieclip on the stage that ive created manualy(it contains some animations).Everything works fine, exept that the movieclip I create with AS, gets on top of the other MC, I want it to be under.I´ve tried to change the depth, but couldnt get it to work.

anyone know how I should solve this?

thanks
