Parsin Error (C#)

Could anyone shed some light, that what the ef is wrong with this script?

 using UnityEngine;
    public class OpenSettings : MonoBehaviour {
    
    public settingsMenu menuScript;
    
    public void OnMouseDown()
    
    {
    menuScript.OpenQualitySettings();
    }

Ive been fighting this script for 4 hours, and simply cannot figure out what is the problem.
OpenSettings is the name of script.

you need a } to close the two open brackets you have put in. @devis

You’re missing a closing } at the end of the class…
