Why isn't this button door script working?

I have a door and two buttons. One button is supposed to make the door transparent, one button is supposed to return it back to its opaque state. Whenever I click one of the buttons, nothing pops up in the output.

Close button:

function onClicked()
	
Script.Parent.Parent.Door.Transparency = 0
Script.Parent.Parent.Door.CanCollide = true

end

Script.Parent.ClickDetector.MouseClick:connect(onClicked)`

Open button:

function onClicked()
	
Script.Parent.Parent.Door.Transparency = 1
Script.Parent.Parent.Door.CanCollide = false

end

Script.Parent.ClickDetector.MouseClick:connect(onClicked)

The "s" in "Script.Parent" is supposed to be lowercased

function onClicked()

script.Parent.Parent.Door.Transparency = 0
script.Parent.Parent.Door.CanCollide = true

end

script.Parent.ClickDetector.MouseClick:connect(onClicked)
