How do I reference int from other script

I am trying to make it so when I click on the object 3 times it will destroy it. This is the script attached to the player.

 public Text MoneyText;
 private int Money;
 private int Clicks1;
 public GameObject Base1;
 public GameObject Basemake;
 private Vector3 BaseSpot;
 private bool basedeath;
 public ClickScript clickscript;
 
 void Start ()
     {
         MoneyText.text = "Money: " + Money;
         Money = 0;
         Clicks1 = clickscript.Clicks;
         basedeath = true;
     }
 
 void Update()
     {
         BaseSpot = transform.position + Base1.transform.position;
 
         if (Input.GetButtonDown ("Fire3")) 
         {
             Instantiate(Basemake, BaseSpot, transform.rotation);
         }
 
         if (Clicks1 == 0)
         {
             if (basedeath) 
             {
                 Base1.gameObject.SetActive (false);
                 Money = Money + 1;
                 MoneyText.text = "Money: " + Money;
                 basedeath = false;
             }
         }
        }

And this is the code attached to the object im trying to destroy

 public int Clicks;

 // Use this for initialization
 void Start () 
 {
     Clicks = 3;
 }

 public void OnMouseDown () 
 {
     Clicks = Clicks - 1;
 }

}
