Cannot access variable of another object's script

In my GUI script I want to set a variable's value to true on another object's script. But it's not working ... :/

Thanks for any help!

The error message:

error CS1061: Type UnityEngine.Object' does not contain a definition for doRotateL' and no extension method doRotateL' of type UnityEngine.Object' could be found (are you missing a using directive or an assembly reference?)

The GUI Script:

 using UnityEngine;
 using System.Collections;
 
 public class GUITest : MonoBehaviour {
 
     public GUISkin mySkin;
     public GameObject bodies;
     private Object rotatorScript;
 
     void Start() {
     }
 
     void OnGUI() {
 
         GUI.skin = mySkin;
 
         GUILayout.BeginArea (new Rect (Screen.width*2/72, Screen.height/3, Screen.width*22/72, Screen.height/3));
         
         if(GUILayout.Button ("MoveBodyLeft", "button")) {
 
             rotatorScript = bodies.GetComponent("ClickRotator01");
             rotatorScript.doRotateL = true;
         }
         
         GUILayout.EndArea ();
     }
 }

The other Object's script:

 using UnityEngine;
 using System.Collections;
 
 public class ClickRotator01 : MonoBehaviour {
 
 public float rotationStepAngle = 30.0F;
 public float timer = 10.0F;
 
 private float rotationToAngle;
 public bool doRotateL = true;
 
      void Start () {
         float rotationToAngle = rotationStepAngle;
     }
 
     void Update () {
         Rotator();
     }
     
     void Rotator()
     {
 
         if(doRotateL){
             
             Quaternion newRotation = Quaternion.AngleAxis(rotationToAngle, Vector3.up);
             transform.rotation = Quaternion.Lerp(transform.rotation, newRotation, Time.deltaTime * timer);
 
             if (transform.rotation == newRotation){
                 
                 transform.rotation = newRotation;
 
                 doRotateL = false;
                 rotationToAngle += rotationStepAngle;
             }
         }
     }
 }
