Assets/Managers/GameEventManager.cs(63,14): error CS0116: A namespace can only contain types and namespace declarations pls look at this script

hello i have 8 errors:
Assets/Managers/GameEventManager.cs(63,14): error CS0116: A namespace can only contain types and namespace declarations
its only (63,14) different whats wrong with this pls look =(

public static class GameEventManager {

    public delegate void GameEvent();

    public static event GameEvent GameStart, GameOver;

    public static void TriggerGameStart(){
	        if(GameStart != null){
		            GameStart();
	        }
    }

    public static void TriggerGameOver(){
	        if(GameOver != null){
		            GameOver();
	        }
    }

}

void Start () {
GameEventManager.GameStart += GameStart;
GameEventManager.GameOver += GameOver;
gameOverText.enabled = false;
}

private void GameOver () {
gameOverText.enabled = true;
instructionsText.enabled = true;
enabled = true;
}

void Update () {
if(Input.GetButtonDown(“Jump”)){
GameEventManager.TriggerGameStart();
}
}
private void GameStart () {
gameOverText.enabled = false;
instructionsText.enabled = false;
runnerText.enabled = false;
enabled = false;
}

private Vector3 startPosition;

void Start () {
GameEventManager.GameStart += GameStart;
GameEventManager.GameOver += GameOver;
startPosition = transform.localPosition;
renderer.enabled = false;
rigidbody.isKinematic = true;
enabled = false;
}

private void GameStart () {
distanceTraveled = 0f;
transform.localPosition = startPosition;
renderer.enabled = true;
rigidbody.isKinematic = false;
enabled = true;
}

private void GameOver () {
renderer.enabled = false;
rigidbody.isKinematic = true;
enabled = false;
}

Place this code:

void Start () { GameEventManager.GameStart += GameStart; GameEventManager.GameOver
+= GameOver; gameOverText.enabled = false; }

private void GameOver () { gameOverText.enabled = true; instructionsText.enabled = true; enabled = true; }

void Update () { if(Input.GetButtonDown("Jump")){ GameEventManager.TriggerGameStart(); } } private void GameStart () { gameOverText.enabled = false; instructionsText.enabled = false; runnerText.enabled = false; enabled = false; }

private Vector3 startPosition;

void Start () { GameEventManager.GameStart += GameStart; GameEventManager.GameOver
+= GameOver; startPosition = transform.localPosition; renderer.enabled = false; rigidbody.isKinematic = true; enabled
= false; }

private void GameStart () { distanceTraveled = 0f; transform.localPosition = startPosition; renderer.enabled = true; rigidbody.isKinematic = false; enabled = true; }

private void GameOver () { renderer.enabled = false; rigidbody.isKinematic = true; enabled
= false; }

inside class declaration.
