Unexpected Symbol 'void'

Hiya,

Alrighty, so, there are a couple issues there. The semicolon is a problem, but when you delete that, you will see other issues and such. So, the problem is that this code isn't inside of a class and it needs to be. I can't quite tell if "target" was supposed to be the name of this class, or if that was supposed to be a variable that you can reference in Unity's inspector window, but try to follow this format for Monobehaviour classes (a Monobehaviour is essentially a script that is part of an object that could be in a scene).

 // Some script for a scene object
 public class ExampleMonobehaviour : MonoBehaviour {
 
     public GameObject target; // A public variable that will show up in Unity's inspector window
 
     void Update() {
         // ...
     }
 
     void OnMouseDown() {
         // ...
     }
 
     void OnMouseUp() {
         // ...
     }
 }
