CloneTrooper cutscene editor plugin scripting help?

So I am using CloneTroopers Cutscene editor I picked the executable local script setting, and put this into a GUI it does nothing. Any suggestions?

function change()
game.Workspace.Cutscenes.ShowIntro.Disabled = false
end

script.Parent.MouseButton1Down:connect(change)

Local scripts will not be executed in the workspace. move it to starterpack instead, and adjust the script accordingly.
