Character not jumping

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

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class playercontroller : MonoBehaviour {
6.  
7.     public Animator animator;
8.  
9.     public float topspeed = 10f;
10.         bool facingRight = true;
11.  
12.     bool grounded = false;
13.  
14.         public Transform GroundCheck;
15.  
16.     float groundRadius = 0.2f;
17.  
18.     public float jumpForce =700f;
19.  
20.     public LayerMask whatIsGround;
21.  
22.  
23.  
24.     void start ()
25.     {
26.         animator = GetComponent<Animator> ();
27.    
28.    
29.     }
30.  
31.  
32.     void FixedUpdate()
33.     {
34.    
35.         grounded = Physics2D.OverlapCircle (GroundCheck.position, groundRadius, whatIsGround);
36.         animator.SetBool("Ground", grounded);
37.  
38.         animator.SetFloat("vSpeed", GetComponent<Rigidbody2D>().velocity.y);
39.  
40.         float move = Input.GetAxis ("Horizontal");
41.  
42.  
43.  
44.    
45.     GetComponent<Rigidbody2D> ().velocity = new Vector2 (move * topspeed, GetComponent<Rigidbody2D> ().velocity.y);  
46.  
47.         animator.SetFloat ("Speed", Mathf.Abs (move));
48.  
49.         if (move < 0 && !facingRight)
50.             Flip ();
51.         else if (move >  0 && facingRight)
52.             Flip();
53.  
54.    
55.     }
56.  
57.     void Update()
58.     {
59.         if (grounded && Input.GetKeyDown (KeyCode.Space))
60.         {
61.             animator.SetBool ("Ground", false);
62.  
63.          GetComponent<Rigidbody2D> ().AddForce (new Vector2 (0, jumpForce));
64.        
65.         }
66.     }
67.  
68.  
69.     void Flip()
70.     {
71.    
72.         facingRight = !facingRight;
73.  
74.         Vector3 theScale = transform.localScale;
75.  
76.         theScale.x *= -1;
77.  
78.         transform.localScale = theScale;
79.    
80.    
81.     }
82.  
83. }

 

This has been resolved, sorry moderators you don't have to pass this through b
