Calling a function from a private static function

hi,
i’m trying to modify some code and can’t figure out what the issue i’m having it. this is the(shortened) code:
public static function Lose():void {
trace(“OVER!”);

        Clock.stop();
                    
        OverIt();

}
public function OverIt(){
MediumButton.visible = true;
}

this is the error i get:

1180: Call to a possibly undefined method OverIt.

i just want to call a function from inside of the public static funtion.

both function are inside this class:

public class Game extends MovieClip {
}

any ideas?
