Jump to frame

i’m still new to this program so this might be a n00b question

in my main movie i set a button to jump to a movieclip (seperate movie) now on press of the same or another button it has to play the same movieclip but beginning on frame 45.

any ideas?

i can get the movie to play.

its a folding shape that gains in width, on frame 45 it starts to fold back in to dissapear.

myMovieClip.gotoAndPlay(45);
