Prefab movement towards target

How to move my prefab towards a target?

I have a missile as a prefab and i want it to move towards enemy ship which is the target.

I have written a script to move the prefab
public Transform target
Void Start()
target = GameObject.find(“Enemy”).transform;

void Update ()
transform.position = Vector3.MoveTowards(transform.position, target.transform.position, 1.0f);

but when i play it says NullReferenceException: Object reference not set to an instance of an object

The method name is “GameObject.Find”, not “GameObject.find”. Methods are case sensitive.

if that isn’t the issue, make sure the name of the gameobject is “Enemy”. These names are case sensitive as well.
