Trying to access the Slider component

[Mr.Happy]

im trying to access the Slider component but there’s no Slider component apparently:

using UnityEngine;
using System.Collections;

public class QSlider : MonoBehaviour {
    private float slider;
    void Start()
    {
        slider = GetComponent<Slider>();
    }
}

and the error is:

And finally the inspector…

Thanks!
