Can't find the error movescript/camera script

Unity Engine

hello , im using this script on my camera and im getting a null reference error

using UnityEngine;
using System.Collections;

public class Camera2D : MonoBehaviour {
	public Transform player;
		
	public float smoothRate = 0.5f;
	
	private Transform thisTransform;
	private Vector2 velocity;
	//arxi
	void start (){
		thisTransform = transform;
		velocity = new Vector2(0.5f,0.5f);
	}
	// Update is called once per frame
	void Update () {
		Vector2 newPos2D = Vector2.zero;
		
		newPos2D.x = Mathf.SmoothDamp(thisTransform.position.x,player.position.x,ref velocity.x,smoothRate);
		newPos2D.y = Mathf.SmoothDamp(thisTransform.position.y,player.position.y,ref velocity.y,smoothRate);
		
		
		Vector3 newPos = new Vector3(newPos2D.x,newPos2D.y,transform.position.z);
		transform.position= Vector3.Slerp(transform.position,newPos,Time.time);
	}
}

and also the player using this scrpit cant move horizontaly

using UnityEngine;
using System.Collections;

public class Controller2D : MonoBehaviour {

	//Vazw to Character Controller
	CharacterController characterController;
	//Elenxos varititas
	public float gravity = 30;
	//movement
	public float walkSpeed = 20;
	public float jumpHeight = 5;
	//Dieuthinsi kinisis
	Vector3 moveDirection = Vector3.zero;
	float horizontal = 0;
	// Otan arixizi to script
	void Start () {
		characterController = GetComponent<CharacterController>();
		horizontal = Input.GetAxis("Horizontal");
	}
	
	// Ana frame
	void Update () {
		//elenxos kinisis pexti 
		characterController.Move(moveDirection*Time.deltaTime);
		//elenxos varititas
		moveDirection.y -= gravity * Time.deltaTime;
		//kinisi deksia
		if(horizontal > 0){
			moveDirection.x = horizontal * walkSpeed;
			}
		//kinisi aristera
		if(horizontal < 0){
				moveDirection.x = horizontal * walkSpeed;
			}	
		//elenxos jump
		if(characterController.isGrounded){
			if(Input.GetButtonDown("Jump")){
				moveDirection.y = jumpHeight;
			}
		}
	}
}

*See the line number in error message.
Could you post full error?

Well, it seems that start() methon should starts with big letter S - Start() in the Camera2D scipt.
Or player variable is not assigned.

void Start (){
        thisTransform = transform;
        velocity = new Vector2(0.5f,0.5f);
    }

Thanks a lot man … That leaves only the movement problem to be solved

Have to update horizontal every frame, not just in start.

Thanks mate, it worked …case closed
