COMPILER ERROR NOT FOUND

I was trying to make my player move and jump but I made a mistake that I can't found. Removing the part that makes the player jump, there's no compiler error, but when I play, after a time it falls into left.

 public float speed;
 private Rigidbody rb;
 private Vector3 movement;
 private int jumping;
 void Start ()
 {
     rb = GetComponent<Rigidbody>();
 }
 void Update ()
 {
     if (Input.GetKeyDown ("space"))(jumping = false){
         Vector3 jump = new Vector3 (0.0f, 500.0f, 0.0f);
         GetComponent<Rigidbody> ().AddForce (jump);
         jumping = true;
     }
 }
 void LateUpdate ()
 {
     if (jumping = true) {
         jumping = false;
     }
 }
 void FixedUpdate ()
 {
     // Store the input axes.
     float h = Input.GetAxisRaw ("Horizontal");
     float v = Input.GetAxisRaw ("Vertical");
     Move (h, v);
 }
 void Move (float h, float v)
 {
     movement.Set (h, 0f, v);
     movement = movement.normalized * speed * Time.deltaTime;
     rb.MovePosition (transform.position + movement);
 }

The player is a capsule with a ball as head. The scales are 1;1;1 (capsule/body) and 1.245381 (sphere/head). The sphere is 1.35 up to the center of the capsule.
