My Unity does not show my MovementSpeed

I wrote this code to make my 2d character move but inside of unity it does not show me my movement Speed

using UnityEngine;

public float MovementSpeed = 1;
public class Character2dMovement : MonoBehaviour
// Start is called before the first frame update
void Start()


void Update()
    var movement = Input.GetAxis("Horizontal");
    Transform.position += new Vector3(movement,0,0) * Time.deltaTime * MovementSpeed;


Please Help i am trying to finish my first game

Your Variable has to be public or [Serilized Field]. Here a C# example:
[SerializeField] float lookspeedY; public float xy;
Both are getting showed in the inpector and can be changed in the inspector, the difference is that the public float can also be acsessed from other scripts too.
