My Space Shooter Mover script is not working in Unity 5

This is the code I typed:

public class Mover : MonoBehaviour
{
	private Rigidbody rb;

	public float speed;

	void Start ()
	{
		rb = GetComponent<Rigidbody>
		rb.velocity = transform.forward * speed;
	}

There is an error where it says "Unexpected symbol ‘rb’
on rb.velocity = transform.forward * speed

hi;

this lane should be change like this :

         rb = GetComponent<Rigidbody>();
