Why is my door opening and closing at the same time?????????

Im not able to open the door and then close it by touch. My script opens the door and closes it immediately. It does not regonize if the boolean is true or not. it plays the animation at the same time. I want to touch the door then it should open. By the second touch it should close.

I tried a lot but no chance to fix it. The script is attachet to a door!!!

heres my script.//////////////////////////////////////////////////

private var focusObj:GameObject=null; // null Bedeutet das es leer ist

var dorop:boolean= false;

function Update ()

{

if(Input.touchCount>0&&Input.GetTouch(0).phase==TouchPhase.Began) // checkt ab ob der finger ber¸hrt

{

     focusObj = null;        // null Bedeutet das es leer ist

     var ray =Camera.main.ScreenPointToRay(Input.GetTouch(0).position);

     var hit : RaycastHit; 


                 if(Physics.Raycast(ray,hit,100000) && hit.transform.tag == "door" && dorop == false)
                 {
                 animation.Play("DoorOpenVorrat");
                 dorop=true;
                 print ("dorop=true");
                 
                 focusObj = hit.transform.gameObject;        // der Var focusObj wird das GameObjekt zugewiesen.
                 }
                 
                 if(Physics.Raycast(ray,hit,100000) && hit.transform.tag == "door" && dorop == true)
                 
                 {
                 animation.Play("Door CloseVorrat");
                 dorop=false;
                 print ("dorop=false");
                 }                
                 
 }


 if (focusObj&&Input.touchCount<0&&Input.GetTouch(0).phase == TouchPhase.Ended) // checkt ab ob der finger noch da ist

 {
 focusObj=null;
 }

}

So why it does not work????? Please can help me someone?????
