How to detect whether the object's position is change?

Hi, I need your help. I try to write little games for children. In my game, users should combine the cube after choosing the right face and direction in terms of the card. In my code, after placing the cube, the drag-drop script is deactivated because, when I do not do this, the game also works on the turns of the cubes, so it gives wrong results. I could not understand why happened so. How can fix that problem? The user can change the location of the cube after placing it in an area. For this reason, the script needs to be activated again. How can I do that? Could you help me?

             Collider col = alan.GetComponent<BoxCollider>();
 
             float distance= Vector3.Distance(alan.transform.position, transform.position);
 
             if (distance<= 4 && distance>= 0)
             {
                 this.enabled = false;    // Deactive the script
 
                 if (whichCubesFace.name == gameArea.name)
