Pass variable from MC to _root

Hi,

I have a movieclip that is loaded from the main timeline. Within that mc I have a button that when clicked I want to pass a variable back to a function within the main timeline.

The below bold string is what I want to pass as a variable from the button click event in the mc to the function LoadGallery in the main timeline.

Code:

---

Defines the xml path to pass to the function

function loadGallery1(){
    loadGallery("Flash/gallery1.xml"); 
}


Calls LoadGallery function and recieves the xml path:

function loadGallery(galName){
    _root.xmlDataPath = galName; 
    mcLoader.loadMovie("Flash/viewer.swf");
}


Calls function to run it:

loadGallery1();

---

All of the above code resides in the main timeline (_root), I don't show a button click event here from the mc because I don't have one. All I need that button click event to do is to populate that bold string above.

Can anyone help me with this?

thanks

Ok, correct me if this is the wrong way of doing things. I solved the problem and heres what I did.

I changed the function that's in the main timeline (_root) to this:

Code:

---

//Set button actions
function loadGallerys(){

//myRootXMLGalleryPath is defined in the buttonClick event
    loadGallery(myRootXMLGalleryPath);
 
}

---

Then in my mc where the button click occurs, I put this in the onRelease function of the button:

Code:

---

//used in the _root timeline.

var mygallery:String = "Flash/gallery1.xml";               
_root.myRootXMLGalleryPath = mygallery
               
_root.play();
        }
}

---

This seems to work for all my buttons now, I just have to define the strings within those button events. Is that the proper way of doing things?

thanks
