Effect only one gameobject when multiply have the same script

Hi guys I'm running into a bit of a jam. I have a targeting system that works like I need how ever when I send messages it gets sent to all the gameobjects with that script I've pasted the scripts below and thanks for your help in advance.

  #pragma strict
 
 //Player Stats
 static var playerhealth : int = 100;
 static var Defense : float = 2;
 
 // Base Damage
 static var baseMin : int = 2;
 static var baseMax : int = 5;
 static var BaseDamage : int;
 
 // Gui Display of hp
 var playerHP: GUIText;
 var player : GameObject;
 
 //Crit Damage 
 static var DmgMin : int = 2;
 static var DmgMax : int = 2;
 static var CritDamage : int;
 
 //Crit Chance
 static var CritMin : int = 1;
 static var CritMax : int = 10; 
 static var CritChance :int;
 
 //Combat Variables's
 var HitAmmount : int;
 var playerhit : int;
 
 //Raycast Variable's
 var distance : float = 30;
 var target : GameObject;
 
 //Displays Current Target
 var LockedOn : GUIText;
 
 function Update () 
 {
 
  if(Input.GetKeyUp(KeyCode.F)) 
      {
      Target();
      }
      if(Input.GetKeyUp(KeyCode.G)) 
      {
      AttackOne();
      }
  
  var txt: String = "Health Points:" +playerhealth;
  playerHP.text = txt;
  
  if ( playerhealth <= 0 )
  playerhealth = 0;
 
 
 }
 function Target () 
 {
  print("locking on");
  
 
  var dir = transform.TransformDirection(Vector3.forward);
  var hit : RaycastHit;
  
  Physics.Raycast(transform.position, dir, hit, distance);
  
  print(hit.collider.gameObject);
 
  target = hit.collider.gameObject;
  
  var LockedName = hit.collider.gameObject.name;
  
  var txt2 : String = " Current Target" + " " +LockedName;
  LockedOn.text = txt2;
 }
 function AttackOne ()
 {
 
  print("Player Atk");
 
  CritChance = (Random.Range(CritMin,CritMax));
  //print(CritChance + " " +"CritChance");
 
  if ( CritChance == 1 )
  {
  BaseDamage = (Random.Range(baseMin,baseMax));
  //print(BaseDamage + " " +"BaseDamage");
  
  CritDamage = (Random.Range(DmgMin,DmgMax));
  //print(CritDamage  + " " +"CritDamage");
  
  HitAmmount = BaseDamage * CritDamage;
  
  target.GetComponent(Enemy).Combat(HitAmmount);
  
  //print(HitAmmount);
  print("Crit");
  }
  else 
  {
  
  BaseDamage = (Random.Range(baseMin,baseMax));
  //print(BaseDamage + " " +"BaseDamage");
  
  CritDamage = (Random.Range(DmgMin,DmgMax));
  //print(CritDamage  + " " +"CritDamage");
  
  
  HitAmmount = BaseDamage;
  //print(BaseDamage + " " +"BaseDamage");
  print("No Crit");
  
  target.GetComponent(Enemy).Combat(HitAmmount);
  }
 
 }

 and here is the enemy script
 
 
 #pragma strict
 
 //Enemy Health
 static var EnemyHealth : int = 100;
 // Gui Display of hp
 var EnemyHP: GUIText;
 
 function Update()
 {
 
  var txt: String = "Enemy Health Points:" +EnemyHealth;
  
  EnemyHP.text = txt;
  
  if ( EnemyHealth <= 0 )
  {
  EnemyHealth = 0;
  Destroy(this.gameObject);
  }
 
 }
 
 function Combat(dmg:int)
 {
  EnemyHealth = EnemyHealth - dmg;
  print("it works");
 }
