actionscript 3 - AS3 how to manipulate different instances of a class from the timeline -

i trying create menu using as3 , cant seem find way finish it. this got far

so wrote class attached movieclip , put several instances of on stage.

package {  import flash.events.event; import flash.events.mouseevent; import fl.transitions.tween; import fl.transitions.tweenevent;  import fl.transitions.easing.*; import flash.display.*;  public class servicesbuttons extends movieclip {      public function servicesbuttons() {          shapemc.width = 0;          this.addeventlistener(mouseevent.roll_over, mouseon);         this.addeventlistener(mouseevent.roll_out, mouseoff);         this.addeventlistener(mouseevent.click, clicked);          function mouseon(e:event) {             var shapegrow:tween = new tween(shapemc, "width", strong.easeout, 0, 200, .3, true);         }          function mouseoff(e:event) {             var shapeshrink:tween = new tween(shapemc, "width", strong.easeout, shapemc.width, 0, .3, true);         }          function clicked(e:event){             removeeventlistener(mouseevent.roll_out, mouseoff);                  removeeventlistener(mouseevent.roll_over, mouseon);         }      }  } 

}

i wanted animation not roll once click on button , wanted animation go once click on different button.

my question is, how proceed here, searched online clues , understood set variables within class , change them on timeline , use event listeners catch changes. tried doing end redundant way gets me nowhere...

i have keep button has been clicked before :

public class servicesbuttons extends movieclip {      private static var activebutton : servicesbuttons;      public function servicesbuttons() {         setlistener();         this.addeventlistener(mouseevent.click, clicked);     }      private function mouseon(e:event) {         var shapegrow:tween = new tween(shapemc, "width", strong.easeout, 0, 200, .3, true);     }      private function mouseoff(e:event) {         var shapeshrink:tween = new tween(shapemc, "width", strong.easeout, shapemc.width, 0, .3, true);     }      private function clicked(e:event){         if(activebutton != this)         {             if(activebutton)                 activebutton.setlistener();             setlistener();             activebutton = this;         }     }      public  function setlistener() : void{             if(haseventlistener(mouseevent.roll_out))             {                 removeeventlistener(mouseevent.roll_out, mouseoff);                      removeeventlistener(mouseevent.roll_over, mouseon);             }else{                  addeventlistener(mouseevent.roll_over, mouseon);                 addeventlistener(mouseevent.roll_out, mouseoff);                 mouseoff(null);             }      }  }
