gotoAndStop after tween finishes - newbie

probably a simple question. how do you use the gotoAndStop after a tween has run?

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

var webdesignTween:Tween = new Tween(webdesign_main, “x”, Back.easeInOut, 1250, 1780, 4, true);
webdesignTween.stop();
var webdesignBtnTween:Tween = new Tween(btn_webdesign, “x”, Back.easeInOut, 240, 770, 4, true);
webdesignBtnTween.stop();
var servicesTween:Tween = new Tween(services_main, “x”, Back.easeInOut, 615, 1145, 4, true);
servicesTween.stop();
var servicesBtnTween:Tween = new Tween(btn_services, “x”, Back.easeInOut, 175, 705, 4, true);
servicesBtnTween.stop();

btn_rates.addEventListener(MouseEvent.CLICK, onClick);
function onClick(e:MouseEvent){
webdesignTween.start();
webdesignBtnTween.start();
servicesTween.start();
servicesBtnTween.start();

// need the gotoAndStop to run after the previous Tweens have run
gotoAndStop(2);
}

btn_services.addEventListener(MouseEvent.CLICK, onClick2);
function onClick2(e:MouseEvent){
webdesignTween.start();
webdesignBtnTween.start();
}
stop();

thanks.
