What is wrong with my script?

I am trying to create a list, and when an object is collected (in this case a bottle) a tick appears next to it.

This is the script that I currently have (c#)

 using UnityEngine;
 using UnityEngine.UI;
 
 public class tick_1_script : MonoBehaviour {
     public RawImage tick;
     public GameObject bottle
 
     // Use this for initialization
     void Start () {
     bottle.enabled = true
     tick.enabled = false
     }
 
     void Update () {
         bottle.enabled = false
         tick.enabled = true
     }
 }

If you can help me, please do as I need it as soon as possible...
