Hi, Im stuck on changing a variable in a JS script from a CS Script. Can I change the variable directly or do I call a function in the JS script from the CS script?

MouseOrbit.js

var target : Transform;
...code

Original Switch.js

function Update () {
    //if (Input.GetButtonDown("Jump"))GetComponent(Follow).target = switchToTarget;
    if (Input.GetButtonDown("Jump")){
    var newTarget = GameObject.Find("Cube1").transform;
    GetComponent(Follow).target = newTarget;
    }
}

The cs script I am trying:

    using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class SceneControl : MonoBehaviour {
    public void  Start (){
        GameObject test = GameObject.Find("Main Camera");
        Debug.Log("Got:" + test.name);
        //MouseOrbit myMS = test.GetComponent<MouseOrbit>();
        //Debug.Log("Got:" + myMS.name);
        Component myMS = GetComponent(typeof(MouseOrbit));
        Debug.Log(myMS.ToString());
        //myMS.target = sceneObj.transform;
    }

I keep getting a NullReferenceException : Object reference not set to an instance of an object. This is for the getComponent call. the GameObject.Find works ok and I get Main Camera back. Is this even possible?

K this works:

            GameObject test = GameObject.Find("Main Camera");
        Debug.Log("Got:" + test.name);
        MouseOrbit myMS = test.GetComponent<MouseOrbit>();
        Debug.Log(myMS.ToString());
        myMS.target = sceneObj.transform;
