Strange error message in console

UnassignedReferenceException: The variable Setup_Tile of Checker has not been assigned.
You probably need to assign the Setup_Tile variable of the Checker script in the inspector.
Checker.Start () (at Assets/Scripts/Checker.cs:10)

It's strange because I *did* assign the Setup_Tile variable of the Checker script in the inspector, and the program is working properly, placing the checkers on their respective setup tiles.

 

Code (CSharp):

1. public class Checker : MonoBehaviour
2. {
3.     // Start is called before the first frame update
4.     void Start()
5.     {
6.         this.transform.position = Setup_Tile.transform.position;
7.     }
8.  
9.     public GameObject Setup_Tile;
10.  
11.     // Update is called once per frame
12.     void Update()
13.     {
14.        
15.     }
16.  
17.     void OnMouseDown()
18.     {
19.         Debug.Log(this.transform.name + ", " + this.transform.parent.name);
20.     }
21. }
22.  

 

Found it. The script was being applied to both the checker container and the checker within it.

Thanks anyway.
