The logic behind what I want to do is very, very simple but somehow it just doesn’t work.

Ok, I have this Main.fla and my Main.as which is the Class Document. In the Main.fla, I have a button in the library whose class is HomeBtn.as. Inside this HomeBtn.as, I have an event listener where the user clicks the button, it will bring the player back to the home page.

In my Main.as, I have a function called gotoFrame, which goes to the frame and does its respective functions.

```auto

private function gotoFrame(frame:String):void
        {
            gotoAndStop(frame);
            
            if (this.currentLabel == "preload")
            {
                trace("Currently at preload");
                
                doPreload();
            }
            else if (this.currentLabel == "storefront")
            {
                trace("Currently at storefront");
                
                gotoStoreFront();
            }
            else if (this.currentLabel == "insideStore")
            {
                trace("Currently inside store");
                
                gotoInsideStore();
            }
        }

```

and so, I’m trying to call this function (which is in the Main.as), from my HomeBtn.as, but somehow it’s not working. My HomeBtn.as:

```auto

package
{
    import flash.display.*;
    import flash.events.*;
    import Main;
    
    public class HomeBtn extends SimpleButton
    {
        
        public function HomeBtn()
        {
            this.addEventListener(MouseEvent.CLICK, gotoFrontStore);
        }
        
        public function gotoFrontStore(e:MouseEvent):void
        {
            this.removeEventListener(MouseEvent.CLICK, gotoFrontStore);
            
            root.gotoFrame("storefront");
        }
    }
}

```

I don’t think I’m doing it correctly, and this simple problem is driving me nuts. Hope someone can help!
