what do i have to fix on my script so the GUI TEXT i added counts and doesnt stay at 0.i added a winText gui text also to display "you winn" after player collects couple of "Gold" gameobjects. here is my script

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

public class SimplePlatformController : MonoBehaviour {

     [HideInInspector] public bool facingRight = true;
     [HideInInspector] public bool jump = false;
     public float moveForce = 365f;
     public float maxSpeed = 5f;
     public float jumpForce = 1000f;
     public Transform groundCheck;
     
     public GUIText CountText;
     public GUIText winText;
     private int count;

     private bool grounded = false;
     private Animator anim;
     private Rigidbody2D rb2d;

     void Start ()
     {
         count = 0;
         SetCountText ();
         winText.text = "";
     }

     void OnTriggerEnter(Collider other)
     {
     if (other.gameObject.gameObject.tag == "Gold")
         {
             other.gameObject.SetActive (false);
             count = count + 1;
             SetCountText ();
         }
     }
     
     void SetCountText ()
     {
         CountText.text = "Count: " + count.ToString ();
         if (count >= 3)
         {
             winText.text = "YOU WIN!";
         }
         
     }

     // Use this for initialization
     void Awake () 
     {
         anim = GetComponent<Animator>();
         rb2d = GetComponent<Rigidbody2D>();
     }

     // Update is called once per frame
     void Update () 
     {
         grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));

         if (Input.GetButtonDown("Jump") && grounded)
         {
             jump = true;
         }
     }

     void FixedUpdate()
     {
         float h = Input.GetAxis("Horizontal");

         anim.SetFloat("Speed", Mathf.Abs(h));

         if (h * rb2d.velocity.x < maxSpeed)
             rb2d.AddForce(Vector2.right * h * moveForce);

         if (Mathf.Abs (rb2d.velocity.x) > maxSpeed)
             rb2d.velocity = new Vector2(Mathf.Sign (rb2d.velocity.x) * maxSpeed, rb2d.velocity.y);

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

         if (jump)
         {
             anim.SetTrigger("Jump");
             rb2d.AddForce(new Vector2(0f, jumpForce));
             jump = false;
         }
     }


     void Flip()
     {
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
 }
