Transitions between external sfws

Hi

I am using Flash CS3 AS2

I have a main movie into which several external swfs are loaded. Two of these swfs are left_menu and middle_menu. I would like these to be able to talk to each other. When the ‘home’ button is pressed on ‘left menu’ I would like ‘middle_menu’ to go to a certain frame and play out. I have had a look at the tutorial which differs a bit and I’m a little confused (very new to actionscript!). I have put on by ‘home’ button if ‘left menu’:

on (press) {
if (_level0.currMovie == undefined) {
_level0.currMovie = “left_menu”;
container35.gotoAndPlay(“menu_out”);
}
}

and in my main timeline I have put in the first frame of the actionscript

var currMovie = “left_menu”

I know I am definitely missing something. Can anybody help?

Many Thanks

Lady Jazz
