Character not jumping

Unity Engine
1

this is my code for my Charater and when I run it i can move but I it does not jump can someone plase help, the animations for idle and run work fine but I cannot jump

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class playercontroller : MonoBehaviour {

    public Animator animator;

    public float topspeed = 10f;
        bool facingRight = true;

    bool grounded = false;

        public Transform GroundCheck;

    float groundRadius = 0.2f;

    public float jumpForce =700f;

    public LayerMask whatIsGround;



    void start ()
    {
        animator = GetComponent<Animator> ();
   
   
    }


    void FixedUpdate()
    {
   
        grounded = Physics2D.OverlapCircle (GroundCheck.position, groundRadius, whatIsGround);
        animator.SetBool("Ground", grounded);

        animator.SetFloat("vSpeed", GetComponent<Rigidbody2D>().velocity.y);

        float move = Input.GetAxis ("Horizontal");



   
    GetComponent<Rigidbody2D> ().velocity = new Vector2 (move * topspeed, GetComponent<Rigidbody2D> ().velocity.y);   

        animator.SetFloat ("Speed", Mathf.Abs (move));

        if (move < 0 && !facingRight)
            Flip ();
        else if (move >  0 && facingRight)
            Flip();

   
    }

    void Update()
    {
        if (grounded && Input.GetKeyDown (KeyCode.Space))
        {
            animator.SetBool ("Ground", false);

         GetComponent<Rigidbody2D> ().AddForce (new Vector2 (0, jumpForce));
       
        }
    }


    void Flip()
    {
   
        facingRight = !facingRight;

        Vector3 theScale = transform.localScale;

        theScale.x *= -1;

        transform.localScale = theScale;
   
   
    }

}
