What is interfering with my Lerp?

[RussellFincher]

Just can’t figure this out. I have an object with the following script attached that can be dragged along the Y axis with a mouse/finger, and when it collides with a trigger, it should lerp to another position. I can get the lerp to work without the dragging script, and the dragging script to work without the lerp, but once I put them together, no lerping happens and the object just snaps to 0,0,0. What about my code is interfering with the lerp?

// DRAGGING VARIABLES

    var moveLimit = .5;
    var collisionMoveFactor = .01;
    var freezeRotationOnDrag = true;
    var cam : Camera;
    private var myRigidbody : Rigidbody;
    private var myTransform : Transform;
    private var canMove = false;
    private var yPos : float;
    private var freezeRotationSetting : boolean;
    private var sqrMoveLimit : float;
    private var camTransform : Transform;

// LERPING VARIABLES

    var isLerping = false;
    var lerpTimer = 0.0;
    var lerpSpeed = 0.1;    
    var Begin_Rotation = transform.eulerAngles;
    var End_Rotation = Vector3(-90,0,0);
    var Begin_Position = transform.position;
    var End_Position = Vector3(-4.229075,3,2.676687);
    
    
    function Start () {
        myRigidbody = rigidbody;    								
        myTransform = transform;  									
        if (!cam) {   												
            cam = Camera.main; 										
        }
        camTransform = cam.transform;								
        sqrMoveLimit = moveLimit * moveLimit;   					
    }
    
    
    function OnMouseDown () {
        canMove = true; 
        freezeRotationSetting = myRigidbody.freezeRotation;
        myRigidbody.freezeRotation = freezeRotationOnDrag;
        yPos = myTransform.position.y;
    }
    
    function OnMouseUp () {
        canMove = false;	
    }

    	if (tag == other.gameObject.tag){
    		isLerping = true;						
    		}
    }
    
    function FixedUpdate () {
      
        if (!canMove) return;
        myRigidbody.velocity = Vector3.zero;
        myRigidbody.angularVelocity = Vector3.zero;
        myTransform.position.y = yPos;
        var mousePos = Input.mousePosition;
        var move = cam.ScreenToWorldPoint(Vector3(mousePos.x, mousePos.y, camTransform.position.y - myTransform.position.y)) - myTransform.position;
        myRigidbody.MovePosition(myRigidbody.position + move);
      
    // LERPING CODE    
            
    	if (isLerping == true){
    		lerpTimer += Time.deltaTime;
    		transform.eulerAngles = Vector3.Lerp (Begin_Rotation, End_Rotation, lerpTimer*lerpSpeed);
    		transform.position = Vector3.Lerp(Begin_Position, End_Position, lerpTimer*lerpSpeed); 
    		}
    	}

most likely you have not given any values for End_Rotation and End_Position at inspector. Move both values to Start()

 function Start () {
myRigidbody = rigidbody;
myTransform = transform;
if (!cam) {
cam = Camera.main;
}
camTransform = cam.transform;
sqrMoveLimit = moveLimit * moveLimit;
End_Rotation = Vector3(-90,0,0);
End_Position = Vector3(-4.229075,3,2.676687);
}
