Animation not being played!

Hello,Im trying to make the closet doors play 2 different animations.I animated the child objects (doors) of the closet and it works great.The problem stands at the part where If I press e (the assigned button) for the second time,the first animation gets repeated instead of playing the other one(the second animation).This is my script :

 #pragma strict
 var rayLength = 2;
 var isOpen1 : boolean = false;
 var isOpen2 : boolean = false;
 var isOpen3 : boolean = false;
 var isOpen4 : boolean = false;
 var dcd1 : GameObject;
 var dcd2 : GameObject;
 var dcd3 : GameObject;
 var dcd4 : GameObject;
 
 
 
 function Start () {
     isOpen1=false;
     isOpen2=false;
     isOpen3=false;
     isOpen4=false;
 }
 
 function Update()
 {
     var hit : RaycastHit;
     var forward = transform.TransformDirection(Vector3.forward);
     
     if(Physics.Raycast(transform.position, forward, hit, rayLength))
     {
         if(hit.collider.gameObject.tag == ("cd1"))
         {        
             if(Input.GetKeyDown("e") && isOpen1==false && !animation.isPlaying)
             {
                 dcd1.animation.Play("OpenDeskDoor");
                 isOpen1=true;
             }
             
             else if (Input.GetKeyDown("e") && isOpen1==true && !animation.isPlaying) {
                 dcd1.animation.Play("CloseDeskDoor");
                 isOpen1=false;
         }
         }
         
         if(hit.collider.gameObject.tag == ("cd2"))
         {        
             if(Input.GetKeyDown("e") && isOpen2==false && !animation.isPlaying)
             {
                 dcd2.animation.Play("OpenDeskDoor");
                 isOpen2=true;
             }
             
             else if (Input.GetKeyDown("e") && isOpen2==true && !animation.isPlaying) {
                 dcd2.animation.Play("CloseDeskDoor");
                 isOpen2=false;
         }
         }
         
         if(hit.collider.gameObject.tag == ("cd3"))
         {        
             if(Input.GetKeyDown("e") && isOpen3==false && !animation.isPlaying)
             {
                 dcd3.animation.Play("OpenDeskDoor");
                 isOpen3=true;
             }
             
             else if (Input.GetKeyDown("e") && isOpen3==true && !animation.isPlaying) {
                 dcd3.animation.Play("CloseDeskDoor");
                 isOpen3=false;
         }
         }
         
         if(hit.collider.gameObject.tag == ("cd4"))
         {        
             if(Input.GetKeyDown("e") && isOpen4==false && !animation.isPlaying)
             {
                 dcd4.animation.Play("OpenDeskDoor");
                 isOpen4=true;
             }
             
             else if (Input.GetKeyDown("e") && isOpen4==true && !animation.isPlaying) {
                 dcd4.animation.Play("CloseDeskDoor");
                 isOpen4=false;
         }
         }
     }
 }
