Can anyone tell why isn't this simple script not Working?

The rest of the script work but in line 10 where it says "game.Worksace.SliderTrap.Slider.CFrame = CFrame.new(-13.868, 4.711, -12.051)" isn't CFraming the Part know as "Slider" Back to it normal Positions.

function onClick()
    script.Parent.BrickColor = BrickColor.new("Really red")
    script.Parent.Parent.Slider.Friction = 0
    script.Parent.Parent.Slider.Anchored = false
    wait(1)
    script.Parent.Parent.Slider.Friction = 1
    game.Workspace.SliderTrap.Slider.Anchored = true
    wait(5)
    script.Parent.BrickColor = BrickColor.new("Camo")
    game.Worksace.SliderTrap.Slider.CFrame = CFrame.new(-13.868, 4.711, -12.051)


end 
script.Parent.ClickDetector.MouseClick:connect(onClick)
