LoadScene not Working

I have been trying to program a game, and my current project includes having a title screen with a play button that takes you to the actual game screen. For some reason after writing the code, clicking the button has no affect on the game. I will post the code below, I would appreciate any help you can provide.
using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class Play : MonoBehaviour {

	public string level;

	void Clicked() {
		if (Input.GetMouseButtonUp(0)) {
			SceneManager.LoadScene("Cookie");
		}
		
	}

}
