Make button clickable

Hello, i am new in unity.

I am trying to change scene on button click, but its not evening writing log in console. What i am doing wrong?

if(GUI.Button(new Rect(Screen.width * 95 / 100, Screen.height * 15 / 100, 0, 0), "START", customStyle)){
                    Debug.Log('Start clicked');
                    menuMode = false;
                    gameMode = true;
                    Time.timeScale = 1;
                Application.LoadLevel("Scene 1. Beginning");
 }

Use Unity5.0 UI system it’s very easy and helpfull and saves a lot of time.

use ` var width : float = 10; var height : float = 10;

if(GUI.Button(new Rect(Screen.width * 95 / 100, Screen.height * 15 / 100, width, height), “START”, customStyle)){
Debug.Log(‘Start clicked’);
menuMode = false;
gameMode = true;
Time.timeScale = 1;
Application.LoadLevel(“Scene 1. Beginning”);` to start with, you can increase the button size by changing the variables height and width in the inspector
