So I’m trying to get a 3, 2, 1 GO! thing going on but It just doesn’t seem to be working, no errors just not working, any help?

     private bool showCountdown;
     private string countdown = "";
     
     void Start () {
         instance = this;
         GameEventManager.GameStart += GameStart;
         GameEventManager.GameOver += GameOver;
         gameOverText.enabled = false;
     }
 
     void Update () {
         if(Input.GetButtonDown("Jump")){
             GetReady();
             GameEventManager.TriggerGameStart();
         }
         if (Input.touchCount > 0){
             GameEventManager.TriggerGameStart();
         }
     }
     
     IEnumerator GetReady () {
         showCountdown = true;
             
         countdown = "3";
         yield return new WaitForSeconds (1.5f);
         
         countdown = "2";
         yield return new WaitForSeconds (1.5f);
         
         countdown = "1";
         yield return new WaitForSeconds (1.5f);
             
         countdown = "GO!";
         yield return new WaitForSeconds (1.5f);
         
 
         showCountdown = false;
         countdown = "";    
                     
     }
     
     void OnGUI(){
         if (showCountdown){    
                GUI.color = Color.red;    
                GUI.Box (new Rect (Screen.width / 2 - 100, Screen.width / 2, 200, 175), "GET READY");
                 
                GUI.color = Color.white; 
                GUI.Box (new Rect (Screen.width / 2 - 90, Screen.width / 2, 180, 140), countdown);
         }    
     }

You are trying to use a coroutne, but i don’t see that you actually start the coroutine anywhere
