Linking between 2 different .swf files

So I have main .swf file(I'll call it movie1) that leads to webpages that are not in the movie. The webpage has a navbar which is a seperate .swf file (I'll call this movie2). I need the buttons on the navbar to link to a certain place in the main movie. Is there a way to use gotoAndplay in movie2 to go to a scene in movie1? How could I make this work? Thanks.

Here you go 'dmore'. This is in AS2.0, I hope this helps... it's really easy to pass info between two flash movies.
Put this code in the first flash file... assuming that a button click will start the process


var mySender:LocalConnection = new LocalConnection();
//
var myText:String;
btnStart.onRelease = function() {
myText = "some variable/text to pass";
mySender.connect("myConnections");
mySender.send("myConnections", "myAction", txtVar);
};


---------------------------------
put this code in the receiving flash file
----------------------------------

var myReceiver:LocalConnection = new LocalConnection();
myReceiver.connect("myConnections");
myReceiver.myAction = function(myText:String) {

//do something with the passed variable in this function

};

I had to modify the code a little bit because I'm using CS4. So I'm getting this error. I was hoping there wasn't much difference between versions.

Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.LocalConnection was unable to invoke callback myAction. error=ReferenceError: Error #1069: Property myAction not found on flash.net.LocalConnection and there is no default value.

mybutton.addEventListener(MouseEvent.CLICK, buttonClicked);
var mySender:LocalConnection = new LocalConnection();



function buttonClicked(event:MouseEvent):void {

var myText:String;
myText = "some variable/text to pass";
mySender.connect("myConnections");
mySender.send("myConnections", "myAction", "s2");
}

Any chance you know how to make this work in 3.0?

sorry... I haven't had time to study AS3 yet... I know it works in AS2 because I use it quite often.

Ok. Im trying this is AS 2.0. I am completely new to actionscript so I'm probably doing something ignorant here. What do I need to plug into this code just so the 2nd file will play go to a certain scene?
