Namespace error with my jump code

So I am trying to make my character jump, here is my code so far... the problem is I am getting an error that says " A namespace can only contain types and namespace declarations" it says the error is in line 49

 using UnityEngine; using System.Collections;
 
 public class robot : MonoBehaviour {
 
 public float maxSpeed = 10f;
 bool fasingRite = true;
  
 Animator anim;
  
 private int jumpheight = 500;
  
 // Use this for initialization
 void Start () 
 {
     anim = GetComponent<Animator>();
 }
  
 // Update is called once per frame
 void FixedUpdate () 
 {
     float move = Input.GetAxis ("Horizontal");
  
     anim.SetFloat ("speed", Mathf.Abs (move));
  
     rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);
  
     if (move < 0 &&!fasingRite)
        Flip ();
     else if(move > 0 && fasingRite)
        Flip ();
  
     if (Input.GetButtonDown("Jump") || Input.GetKey("space")){
 }
  
 void Flip ()
 {
     fasingRite = !fasingRite;
     Vector3 theScale = transform.localScale;
     theScale.x *= -1;
     transform.localScale = theScale;
 }
 }

 void Jump (){ rigidbody.AddForce(new Vector3(0, jumpheight,0), ForceMode.Force);
