How do I call a variable from another script? (C#)

Hi, I’m trying to call a variable from another script, this variable is inside of a namespace., so I’m having trouble to archieve this.

THE SCRIPT TRYING TO ACCESS THE VARIABLE:

using System;

using UnityEngine;

[RequireComponent(typeof(UnityFunction.Class_One))]

public class Class_Two : MonoBehaviour
{
private UnityFunction.Class_One the_other_var;
public string the_string;

void Start()
{
       the_other_var = GetComponent<Tractor_Speed> ();
}

void Update()
{
       the_string = the_other_var.the_var;
}

}

THE SCRIPT WITH THE VARIABLE:

using System;

using UnityEngine;

namespace UnityFunction
{

public class Class_One : MonoBehaviour
{
public string the_var;

    void Start()
    {
           the_var = "Hi";
    }
}

}

You can add a using statement at the beginning of the script, like

using UnityFunction;
