How do I fix this script?

F = GetMouse()

function Clicked()
	workspace.Door.CanCollide = false
	workspace.Door.Transparency = 0.5
	wait(3)
	workspace.Door.Transparency = 0
	workspace.Door.CanCollide = true	
	
	
end
workspace.Button.F.Button1Down:connect(Clicked)

I can't seem to figure out how to get the Click event to work. What do I need to do to fix this? Or what needs to be added and taken out?
