Move Character Controller

Hello Unity3D.I have a problem with my character controller.My problem is that the character controller that i have assigned to the my characters whenever i add for to the character controller to move the character forward the character controllers moves forward but it doesn't stick the the position that i have assigned to.For example.My character is suppose to move forward the the opponent and then its suppose to stop by the opponent. but when i move the character controller from the new position the character controller starts from point (A).If anyone knows why this happens?Can you please tell me how i can fix this?Or a different way to move the character controller to the opponent smoothly?

Ps. Heres the Script var myTransform : Transform;
function Awake() { myTransform = transform; }

 function Start()
 {
  
 target = GameObject.FindWithTag("Dummy").transform;
  
 }
 
 
 function Update ()
 
 {
 
     if(Input.GetKeyDown("c")) {
     animation.Play("Genzu_Palm");    
     Instantiate(Genzu,spawn.transform.position,spawn.transform.rotation);
     myTransform.rigidbody.AddForce(transform.forward * 500, ForceMode.Impulse);
     Switch();
 
     }
 
 }    
 
 function Switch()
 
 {
     yield WaitForSeconds(2.5);
         animation.Play("Genzu_Palm_Part_2");
         myTransform.rigidbody.velocity = new Vector3(0,0,0);
         Switch2();
             
 }        
     
 function Switch2()
 {
     yield WaitForSeconds(.5);
         animation.Play("Genzu_Palm_Part_3");
         
 }
