Change static variable in JS through Csharp

Question

Hi. I am working on a script to change a variable of a JS script through a C#

my JS:

 static var counter : int = 10 + counter2; 
 static var counter2 : int = PlayerPrefs.GetInt("CubeCoin");
 
 function Update(){
 CubeCoin.counter = 10 + counter2;
 
 if(CubeCoin.counter2>=0){
 CubeCoin.counter2=0;
 }
 }

my C#

 using UnityEngine;
 using System.Collections;
 
 public class CSharp2 : MonoBehaviour 
 {
     //create a variable to access the JavaScript script
     static CubeCoin jsScript; 
 
     void Awake()
     {
         //Get the JavaScript component
         jsScript = this.GetComponent<CubeCoin>();
     }
     

     void OnGUI()
     {
         if (GUI.Button (new Rect (15, Screen.height-Screen.height/5, Screen.width/6, Screen.height/13), "bla")) {
             jsScript.counter2 +=1;
         }
     }
 }

but this don`t work. i got error CS0176 Static member CubeCoin.counter2 cannot be accessed with an instance reference, qualify it with a type name instead. how can i fix that ? and i have to leave the variable static.

A static member belongs to the class itself, and not to a particular object that has that type. So, it's incorrect to try an access a particular instance of that class through GetComponent(). Instead, you need to use the class:

 // replacement for line 19
 CubeCoin.counter2 += 1;

If you are not familiar with static members, take a look at the GameObject class:

http://docs.unity3d.com/ScriptReference/GameObject.html

Lots of the variables apply to regular game objects in your scene. Near the bottom of the page is a section titled "Static Functions". This section describes the static functions of the GameObject class. If you look at the documentation for the Find() function you'll see that you use GameObject.Find() - that's to say you use the class name and not a variable set to a particular game object.
