Resize mc

Hello everyone

How can I make a button to have 2 function
ONE

clip.maximize.onRelease = function() {
clip._width = Stage.width;
clip._height = Stage.height;
trace("Stage width: “+Stage.width+” - This width: "+this._width);
trace("Stage height: “+Stage.height+” - This height: "+this._height);
};

TWO

clip.maximize.onRelease = function() {
clip._width = 500;
clip._height = 400;
};

Thank you in advance
