BCE0005: Unknown identifier

I have problem with accesing to other script it’s first script that I attach to camera

using UnityEngine;

[AddComponentMenu("Colorful/Radial Blur")]
public class CC_RadialBlur : MonoBehaviour
	public float amount = 0.1f;
	public Vector2 center = new Vector2(0.5f, 0.5f);
	public int quality = 1;

	public Shader shaderLow;
	public Shader shaderMed;
	public Shader shaderHigh;

	private Shader _currentShader;
	private Material _material;

second script :

#pragma strict
#pragma implicit

	var kamerka : Camera;

	function Start () {

	function Update () {
	blur = kamerka.GetComponent(CC_RadialBlur).amount;
	blur = 1.0f; 

and my error
