My script doesn't work..Moving the player..Space shooter tutorial.

Hi everyone,
I’m just following the Space shooter tutorial,here I got an error while moving the player.Can anyone please help me…I’m new to gaming.I’m using Unity 5.4…
And here is my script…

using UnityEngine;
using System.Collections;

public class Playercontroller : MonoBehaviour
private Rigidbody;
{
	void Start ()
	{
		rb=Getcomponent<Rigidbody>();
	}
	void FixedUpdate()
	{
		float moveHorizontal = Input.GetAxis ("Horizontal");
		float moveVertical = Input.GetAxis ("Vertical");
	
		Vector3 movement= new Vector3 (moveHorizontal, 0.0f, moveVertical);
		rb.velocity = movement;

	}
}

And the error shows
Assets/Scripts/Playercontroller.cs(5,7): error CS1031: Type expected

Please help me…
thank you …

Here’s the code that works:

using UnityEngine;
using System.Collections;


public class PlayerController : MonoBehaviour {
    public Rigidbody rb;
    public float speed;
  

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        rb.velocity = movement * speed;
    }
}

This:

private Rigidbody;
{

should be this:

{
    private Rigidbody rb;

Also… Getcomponent should be GetComponent. Code is case sensitive!

Hi everyone,
Thank you for your help,

I added code sujjested by @anarhist1994

It shows no errors…

I entered play mode and hit play button…It don’t move.

I taught to change the speed and gave “speed value = 100”…

Still its not working for me…

I’m attaching the screenshot of my work…Please help me…

Thank you…

private Rigitbody rb; is wrong, it must be public Rigitbody rb;

you solve it? i meet the situation,i try to print the value of the var “moveHorizontal”, and it show always
“0” when i press 'wasd". i guess the unity platform in windows 10 , the input doesn`t good match with keyboard. then i check Edit–> Project setting–>input ,the property “moveHorizontal” does be '‘ad’,so i thought there exists some bugs in win10,or some step i losed. no anyidea!
