Help with loadmovie action, one works, other doesn't

My scene has buttons on the main stage that load other swf files into the movie.
they work just fine.

As I drag another movie clip onto the stage called ‘menu’ with buttons.
I try and use the same actionscript to load one of the same swf;s using ‘menu’s’ buttons.
My script does not work when the buttons sit in a seperate movie clip.
I think there is something wrong with the parent/child relationship.

Will someone look at it for me.
I will upload it if you agree
Thanks
