Getting error CS1519: Unexpected symbol `(' in class, struct, or interface member declaration

I am a first time beginner at scripting and I am making a FPS and you have to pick up ammo and it shows on the screen how much ammo you have. I can’t figure out what is causing this error. Here is the script:

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {
	
	public float movementSpeed = 5.0f;
	public float mouseSensitivity = 7.0f;
	float verticalRotation = 0;
	public float UpDownRange = 60.0f;
	public GUIText countText;
	private int count;

	
	// Use this for initialization
	void Start () 
{
		Screen.lockCursor = true;
		count = 0;
		SetCountText ();
}
	
	// Update is called once per frame
	void Update () 
{
		
				//rotations
		
				float rotLeftRight = Input.GetAxis ("Mouse X");
				transform.Rotate (0, rotLeftRight, 0);
		
				verticalRotation -= Input.GetAxis ("Mouse Y");
				verticalRotation = Mathf.Clamp (verticalRotation, -UpDownRange, UpDownRange);
				Camera.main.transform.localRotation = Quaternion.Euler (verticalRotation, 0, 0);
		
				//movement
		
				float forwardspeed = Input.GetAxis ("Vertical") * movementSpeed;
				float sidespeed = Input.GetAxis ("Horizontal") * movementSpeed;
		
				Vector3 speed = new Vector3 (sidespeed, 0, forwardspeed);
		
				speed = transform.rotation * speed;
		
				CharacterController cc = GetComponent<CharacterController> ();
		
				cc.SimpleMove (speed);
}

	void OnTriggerEnter(Collider other)
{
		countText.text = "Count: " + count.ToString ();
}

{
				if (other.gameObject.tag == "PickUp") 
{
			other.gameObject.SetActive (false);
			count = count + 1;
			SetCountText ();
}

}

{
void SetCountText ()
}
				
}

Your bracketing for your last to methods in the class are seriously messed up. They should be:

void OnTriggerEnter(Collider other)
{ 
	countText.text = "Count: " + count.ToString (); 
	
	if (other.gameObject.tag == "PickUp")
	{ 
		other.gameObject.SetActive (false); count = count + 1; SetCountText ();
	}
}

void SetCountText (){ }

Line 54’s { needs to be removed, as it’s not opening anything.

    void OnTriggerEnter(Collider other)
{
       countText.text = "Count: " + count.ToString ();
}
 

          if (other.gameObject.tag == "PickUp") 
{
         other.gameObject.SetActive (false);
         count = count + 1;
         SetCountText ();
}
