Controlling Loaded Movie? Must be simple!

I have a little problem here, that I believe is so Very simple for any of you guys out there, working with flash regularly, to answer…

I have my main Flash File, index.swf… This consists of two scenes, a preloader (Scene 1) and my main timeline (Scene 2)… in my main timeline I load a New movie into a dummy, with the call of a button…

on (release) {
loadMovie(“News.swf”,"/News Dummy");
}

(this loaded movie also consist of two scenes, where scene 1 is a Preloader and scene 2 my main timeline of this movie)

Now, when My movie News.swf has loaded and is stoped in Scene 2 / frame 1 I want to Control this Movie from another Button in my main Timeline of index.swf… making News.swf go to Frame 2 of Scene 2.

THIS CANNOT BE SO DIFFICULT!!! Guess I just dont work with flash to often!!!

Hope One of you guys would explain this to me!!!

Would be greatly Appriciated!!!
