BCE0051: Operator '<' cannot be used with a left hand side of type 'Object' and a right hand side of type 'float' !!!

hello , im doing a Ai script that when you approche to the gameObject it will start following you ( i’m sure it’s a classic basic script for Pro’s :wink: ) but im get tree same Errors:
-BCE0051: Operator ‘<’ cannot be used with a left hand side of type ‘Object’ and a right hand side of type ‘float’

in line 29.22
in line 36.22
and
in line 42.22

pragma strict
 var Distance;
var lookAtDistance : float = 25;
var attackRange : float = 15;
var animator : Animator;

var target : Transform; 
var moveSpeed : float= 0;
var rotationSpeed: float = 1; 

private var myTransform : Transform; //current transform data of this enemy
private var controller : CharacterController;
 
function Awake()
{
    myTransform = transform; //cache transform data for easy access/preformance
    controller = GetComponent(CharacterController); // cache the CharacterController
}
 
function Start()
{
    target = GameObject.FindWithTag("Player").transform; //target the player
}
 
function Update () 
{
Distance = Vector3.Distance(target.position, transform.position);
	
	if (Distance < lookAtDistance)
	{
		animator.SetBool("idle" , true);
		animator.SetBool("walk" , false);
		
	}
	
	if (Distance > lookAtDistance)
	{
		animator.SetBool("idle" , true);
		animator.SetBool("walk" , false);
	}
	
	if (Distance < attackRange)
	{
		animator.SetBool("idle" , false);
		animator.SetBool("walk" , true);
		
	}



    // find the target direction:
    var dir: Vector3 = target.position - myTransform.position;
    dir.y = 0; // ignore height differences to avoid enemy tilting
    //rotate to look at the player
    myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(dir), rotationSpeed*Time.deltaTime);
    //move towards the player:
    controller.SimpleMove(myTransform.forward * moveSpeed);
}

at first i thought puting float’s would work on the variables but it don’t please help me!!

You did not give ‘Distance’ a type. Change line 2:

var Distance : float;

Without implicitly or explicitly giving a variable a type, the variable will be of type ‘object’. The compiler cannot compare something of type object with something of type float.
