Get variable from seperate script.

Hi, I know this question is quite common but I'm a total newbie to C# I would like the variable isShowingMouse to be able to be changed from a second script so that I can disable the mouse when ever an object is clicked on. My mouse code works, I just can't get the other script to interact with it. I get the error "An object reference is required to access non-static member MouselockC.isShowingMouse'" and the error "The name isShowingMouse' does not exist in the current context". Heres the code I have so far.

This is my mouse script that works

 using UnityEngine;
 using System.Collections;
 
 public class MouselockC : MonoBehaviour {
 
     public bool isShowingMouse = true;
     
     void Start(){ 
 
         ToggleMouse(false); 
     }
     
     void Update()
     { 
         if(Input.GetMouseButtonDown(0))
         { Fire(); }
         if(Input.GetKeyDown(KeyCode.E))
         { ToggleMouse(!this.isShowingMouse); }
     }
     
     public void ToggleMouse(bool showMouse)
     {
         Screen.lockCursor = !showMouse;
         Screen.showCursor = showMouse;
         
         this.isShowingMouse = !this.isShowingMouse;
     }
     
     private void Fire()
     {
         Transform cameraTransform = Camera.main.transform;
         Ray fireRay = new Ray(cameraTransform.position, cameraTransform.forward);
         
         RaycastHit hit;
         if(!Physics.Raycast(fireRay, out hit))
         { return; }
         
         Debug.Log("Hit: " + hit.collider.name);
     }
 
 
 }

And here is the script I am trying to use control the above script.

 using UnityEngine;
 using System.Collections;
 
 public class Free_Mouse : MonoBehaviour {
     
 
     // Use this for initialization
     void Start () {
         GameObject teleport = GameObject.FindGameObjectWithTag("teleport");
         teleport.GetComponent<MouselockC>();
         
     }
     
     // Update is called once per frame
     void Update () {
 
         isShowingMouse = MouselockC.isShowingMouse;
 
         //hasForce = script.isShowingMouse(); 
 
         if(MouselockC.isShowingMouse == false)
         { 
             Debug.Log("Pressed left click.");
         }
     }
 
 
     void OnMouseDown(){
         Destroy (this.gameObject);
         MouselockC.isShowingMouse = false;
     }
 }

Thanks so much for any help!
