Scene Manager error in 5.5

Unity Engine
1

I’m attempting to go through the Creating A Main Menu tutorial but I’m stuck with this error.

" error CS0234: The type or namespace name SceneManagment' does not exist in the namespace UnityEngine’. Are you missing an assembly reference?"

My script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagment;


public class LoadSceneOnClick : MonoBehaviour 
{
	public void LoadByIndex (int sceneIndex)
	{
		SceneManager.LoadScene (sceneIndex);
	}
}

What version of Unity are you using?

5.5.0f3

Typo. You’re missing an ‘e’.

using UnityEngine.SceneManagement;
