How do I disable this script when I hit the gui button?

here's the script

-- Constants -- local Camera = game.workspace.CurrentCamera local Player = game.Players.LocalPlayer

-- Camera -- repeat wait() until Player.Character

Camera.CameraType = "Scriptable" Camera.CFrame = game.Workspace.CamPart.CFrame

script.Parent.Enabled = true

here's an image of the button

Any help would be appreciated!
