"The script needs to derive from Monobehavior","The script needs to derive from Monobehaviour"

I'm pretty new to both C# and Unity so I'm having a little difficulty with this code. Every time I try to add my script to an object I keep getting the "script needs to derive from monobehaviour" error. The class name and file names are the same also the Monobehavior line is added after the class name. Any help would be appreciated!

Here is the code:

using UnityEngine;

using System.Collections;

public class Touch : MonoBehaviour {

private Controls player;

 void Start()
 {
     player = FindObjectOfType<Controls>();
 }

 public void LeftArrow()
 {
     player.moveright = false;
     player.moveleft = true;
 }
 public void RightArrow()
 {
     player.moveright = true;
     player.moveleft = false;
 }
 public void ReleaseLeftArrow()
 {
     player.moveleft = false;
 }
 public void ReleaseRightArrow()
 {
     player.moveright = false;

 }

} ,I'm pretty new to both C# and Unity but when I try to add my script to an object I keep getting the "script needs to derive from monobehaviour" error. The class and the file are named the same thing and I have the Monobehavior line directly linked after the class name.

Here's the code:

using UnityEngine; using System.Collections;

public class Touch : MonoBehaviour

{ private Controls player;

 void Start()
 {
     player = FindObjectOfType<Controls>();
 }

 public void LeftArrow()
 {
     player.moveright = false;
     player.moveleft = true;
 }
 public void RightArrow()
 {
     player.moveright = true;
     player.moveleft = false;
 }
 public void ReleaseLeftArrow()
 {
     player.moveleft = false;
 }
 public void ReleaseRightArrow()
 {
     player.moveright = false;

 }

}
