Here is the code I am using to change the alpha of a button when pressed:

on(release){  
setProperty(this,\_alpha, “50”);  
incorrectSound = new Sound();  
incorrectSound.attachSound(“Buzzer”);  
incorrectSound.start()  
incorrectSound.setVolume(25)

\_root.answer = “That is partially correct.”;  
\_root.total = \_root.total+0  
}

However, when I press the button - the whole page, not just the button, changes its alpha. Can anyone tell me why?

Thank you.
