Problem with Scrip for sprites

Hi guys, im following the 2D Character Controller tutorial on Unity website and i tried a script for my 2D game. When i compile it, it keeps pointing me out errors that i cant correct. Here is the script:

using UnityEngine; using System.Collections;

public class TLOscriptcontrol : MonoBehaviour {

 public float maxSpeed = 10f;
 bool facingRight = true;
 
 void Start ()
 {}
 
 void FixedUpdate ()
 {
     float move = Input.GetAxis ("Horizontal");
     
     rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D().velocity.y);
     
     if(move > 0 &&!facingRight)
         Flip();
     else if(move < 0 && facingRight)
         Flip();
 }
 
 void Flip()
 {
     facingRight = !facingRight;
     Vector3 theScale = Transform.localScale;
     theScale.x *= -1;
     Transform.localScale = theScale;
 }

}
