GetChildren [CanCollide/Transparency Onclick?]

I'm trying to make the Children of these bricks CanCollide True/False And transparency change OnClick. Here's my Script.

local isOn = true

function on() isOn = true script.Parent.Pos1.GetChildren().CanCollide = true script.Parent.Pos1.GetChildren().Transparency = 0 script.Parent.Pos2.GetChildren().CanCollide = false script.Parent.Pos2.GetChildren().Transparency = 1 end

function off() isOn = false script.Parent.Pos1.GetChildren().CanCollide = false script.Parent.Pos1.GetChildren().Transparency = 1 script.Parent.Pos2.GetChildren().CanCollide = true script.Parent.Pos2.GetChildren().Transparency = 0 end

function onClicked()

if isOn == true then off() else on() end

end

script.Parent.Pos1.GetChildren().ClickDetector.MouseClick:connect(onClicked) script.Parent.Pos2.GetChildren().ClickDetector.MouseClick:connect(onClicked)

on()
