sorry. but liike i said...... IF your file is set up correctly, that will work.
i assumed you have a main timeline, with a movieclip "A" ( you'll have to call it whateer you want, and change the insance name in the code) that has its own timeline. inside movieclip A is movieclip B.
if so, then yoiu are calling the button/movieclip B by its patway: movieclipA.movieclipB and you are telling movieclip A to goto and Play from its frame one :
movieclipA.gotoAndPlay(1) is the way to do it.
i did fully test it out .....
your error statement says that either you have things named differently, or your code is misplaced - all code should be on the first frame of the main timeline and not inside any movieclip.
i would have no idea what "..Symbol=INFOMERCIALS, layer=VI Statement.." is
however, the full code on the first frame of the main timeline would look something like this: stop();
