Play specific frame of movieclip from other movieclip

[udit19]

now this may look like simple stuff but it is not happening.
i ve made two movieclips 'menuball' which is animates the small ball inside the scene (like a bullet for menu item) and 'menumain' where 'menuball' is embedded and small text which is button.
now i want when this button in 'menumain' is pressed. the 'menuball' clip shud be played from 12th frame onwards. this will basically withfraw the ball from the scene. i ve used simple code
on(release)
{menuball.gotoAndPlay(12);
}
or
this.menuball.gotoAndPlay(12);
or
_root.menumain.menuball.gotoAndPlay(12);

Hi,

From your description, the path would be ....

_root.menumain.menuball.gotoAndPlay(12);

Something else you can try is removing the button object code and using frame code. Give your button an instance name and on the first frame of the movie, use something like.....

_root.movieClipName.buttonName.onRelease=function(){
_root.menumain.menuball.gotoAndPlay("frameLabel");
}

Using frame labels to target makes navigation a bit easier to understand.

hope it helps
