Scripting Errors

First off I am a total scripting noob, but i am getting an error CS1525 unexpected symbol "if" I realize this is commonly because of out of place braces but I dont know where i need to fix it. Also have a parsing error on that last } where I thought it should go, guess not. Any help?

 using UnityEngine;
 using System.Collections;
 
 public class Select : MonoBehaviour {
 public RaycastHit hit;
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
       Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width/2,Screen.height/2,0))    
 
       if(Physics.Raycast(Ray, out hit, 10)) {
             Debug.Log("Hit");
       }
     }
 }
