Change and Access another scripts Variables

I need to change and access another scripts variables in c# i have seen many answers to this question except none of them are in c# so I keep getting some sort of syntax error. Here is my code.

 using UnityEngine;
 using System.Collections;
 
 public class Camera : MonoBehaviour 
 {
     public GameObject Player;
     public GameObject Camera1;
     public GameObject Side1;
     public GameObject Side2;
     public GameObject Side3;
     public GameObject Side4;
     public float DistanceX;
     public float DistanceY;
     public float DistanceZ;
     public float RotationX;
     public float RotationY;
     public float RotationZ;
     public float Width = Screen.width/2;
     public float Height = Screen.height/2;
     public string Position = "First";
     public bool EscClicked = false;
     public var MovementScript = GetComponent(Movement);
     //Movement MovementScript = GetComponent<Movement>();
     
     // Use this for initialization
     void Start () 
     {
         
     }
     
     // Update is called once per frame
     void Update () 
     {
         if(EscClicked == false)
         {
         if(Input.GetKeyDown(KeyCode.Alpha2))
             {
                 Position = "Second";
                 MovementScript.Mode = 1;
             }
             if(Input.GetKeyDown(KeyCode.Alpha3))
             {
                 Position = "Third";
                 movementScript.Mode = 1;
             }
             if(Input.GetKeyDown(KeyCode.Alpha4))
             {

EDIT: I have No idea how to set it up in c# so I don't know what the syntax error is with this code the error is: The contextual keyword var may only appear within a local variable deceleration
