Passing vars to another movie

ok i have a movie loaded into another movie using loadMovie.
now on my main movie i have a Mc button which has a button in it. Now on the button i have
_level1.page1.var_page =“hey”;

now on my loaded movie which is in level 1 i have an mc with instance called page1.
Soo i want it where when you click button in main movie the var to change to “hey” but it does not work. WWhat am i doing wrong?

please someone tell me. And another question. When you have a variable in a frame can other MCs or keyframes access it or what?
