Target touching enemy collision

Question

I can't figure out how to make a target block (isTrigger collider) that is attached to my character detect if it is touching an enemy(rigidbody with an attached isTrigger collider), and if so destroy it with the press of a button. I've tried OnTriggerStay but it doesn't exactly work. Here's what I have so far

 function OnTriggerStay ( other : Collider )    //Rigidbody a Character Controller must be on the the target enemy for this to work 
 {
     if (other.gameObject.tag == "enemy" && Input.GetButton("B"))
     {
         print ("Touching enemy");
     }
     if(other.gameObject.tag == "item" && Input.GetButton("B"))
     {
         print("I picked up an item");
     }
 }

Please help!

Nevermind I fixed my own problem after 5 days For those who need reference, this is my final result

var player : Transform;

 enum TargetTouch 
 {
     none = 0,
     item = 1,
     enemy = 2
 }
 
 var targetState = TargetTouch.none;
 var changeArea : boolean = false;
 
 var canAttack : boolean = false;
 var canPickup : boolean = false;
 
 var otherObj : GameObject;
 var kill : boolean = false;
 
 function Update () 
 {
     var playDir = player.GetComponent("1P Attack");
     kill = false;
     
     if ( changeArea )
     {
         SetTarget();
     }
     
     if (canAttack)
     {
         if(Input.GetButtonDown("B"))
         {
             Destroy(otherObj);
         }
     }
     if (canPickup)
     {
         if(Input.GetButton("A"))
         {
             Destroy(otherObj);
         }
     }
     
     /*if (playDir.direction == 0) //no buttons
     {
         transform.position = player.transform.position;
     }*/
     if ( playDir.direction == 1) //north
     {
         transform.position.x = player.transform.position.x;
         transform.position.y = player.transform.position.y + 1.1;
     }
     if ( playDir.direction == 2) //east
     {
         transform.position.y = player.transform.position.y;
         transform.position.x = player.transform.position.x + 1.1;    
     }
     if ( playDir.direction == 3) //south
     {
         transform.position.x = player.transform.position.x;
         transform.position.y = player.transform.position.y - 1.1;
     }
     if ( playDir.direction == 4) //west
     {
         transform.position.y = player.transform.position.y;
         transform.position.x = player.transform.position.x - 1.1;
     }
 }
 function OnTriggerEnter ( other : Collider )    //Rigidbody or a Character Controller must be on the the target enemy for this to work 
 {
 
     if (other.tag == "enemy" )//&& Input.GetButton("B"))
     {
         otherObj = other.gameObject;
         changeArea = true;
         print ("Touching enemy");
         targetState = TargetTouch.enemy;
     }
     if(other.tag == "item" )//&& Input.GetButton("A"))
     {    
         otherObj = other.gameObject;
         changeArea = true;
         print("I picked up an item");
         targetState = TargetTouch.item;
     }
 }
 function OnTriggerExit ( other : Collider )
 {
     print ("nothing");
     otherObj = null;
     changeArea = true;
     targetState = TargetTouch.none;
     changeArea = false;
 }
 function SetTarget ()
 {
     switch ( targetState )
     {
         case TargetTouch.none :
             canAttack = false;
             canPickup = false;
             changeArea = false;
             break;
         case TargetTouch.item :
             canPickup = true;
             canAttack = true;
             changeArea = false;
             break;
         case TargetTouch.enemy :
             canPickup = false;
             canAttack = true;
             changeArea = false;
             break;
     }
 }
 function Kill ( GameObject )
 {
     kill = true;
 }
