Cs8025 need hepl!!!!!!!!!!!

using UnityEngine;
using System.Collections;

public class cam folllow : MonoBehaviour {

public float interpVelocity;

public float minDistance;

public float followDistance;

public GameObject target;

public Vector3 offset;

Vector3 targetPos;

void Start ()
{
	targetPos = transform.position;
}
	
void FixedUpdate () 
{
	if (target)
	{
		Vector3 posNoZ = transform.position;
		posNoZ.z = target.transform.position.z;

		Vector3 targetDirection = (target.transform.position - posNoZ);

		interpVelocity = targetDirection.magnitude * 5f;

		targetPos = transform.position + (targetDirection.normalized * interpVelocity * Time.deltaTime); 

		transform.position = Vector3.Lerp( transform.position, targetPos + offset, 0.25f);

	}
}

}

Nothings wrong except change this

public class cam folllow : MonoBehaviour {

to this

public class camFolllow : MonoBehaviour {
