Generating enemies dynamically to be attached to enemt prefab

Hello everyone…

i been trying to figure out this issue for few hours…

Im not that good with programming…

I have this script attached to my enemy GameObject… I made some modification so
it could be attached to an enemy prefab so i could generate it dnamically

I have this error which i cant seem to fix it…!!!

The script basically do these things…

-Chech if the player whithen range.
-Follow the player
-if whithen a range it will change the animation
-and the attack script work

I keep getting this error:-

Unknown identifier: ‘Player’
in 5 locations…
All i wanted to do is to generate the Player data dynamically so it will be usable on any object prefab…

Please help me out…

    var MoveSpeed = 2;
    var MaxDist = 25;
    var MidDist = 8;
    var MinDist = 3; 
    public var Health = 100; 

var player : Transform; //current transform data of this enemy
    var target : Transform; //the enemy's target
    var attackTimer : float = 2;
    var coolDown : float = 2;
    var damage : int = 10;               
                         
    function Start ()

    }
     
    function Update ()

     	}

		     	Destroy(gameObject, 2);
	     	}
	    	
	    }     
          
                    
	    if(Vector3.Distance(transform.position,Player.position) <= MaxDist && Vector3.Distance(transform.position,Player.position) < MidDist)
	    {
	        if(Health >=1){
	        
	             if(attackTimer > 0){

			     }
			    if (attackTimer < 0){
			    	attackTimer = 0;
			     }
			    if(attackTimer == 0){
			    	Attack();
			    	attackTimer = coolDown;
			    }

	     		
	     	}else if (Health <= 0){
		     	animation.CrossFade("diehard");
		     	Destroy(gameObject, 2);
	     	}
	    	
	    }
     
    } 
    }

	public function applyDamage(health : int){
	
		Health = Health - health;
	
	}
    function Attack() {

    var go = GameObject.Find("FirstPersonController");
    go.GetComponent(playerHealth).AddjustCurrentHealth(-damage);
    
    } 

function gotHit(){
animation.CrossFade("resist");
yield WaitForSeconds(1);
}

function Test(){
Debug.Log(this.name);
}

Scripts are case sensitive. “var player” should be “var Player”.
