Global events through local scripts?

Morning, SB!

script.Parent.launch.MouseButton1Click:connect(function()
	
	while CountDown > 0 do
		CountDown = CountDown - 1
		script.Parent.ImageLabel.COUNT.Text = CountDown
		wait(2)
	end
	
	script.Parent.ImageLabel.COUNT.Text = "WE HAVE LIFT-OFF"
	
	game.ReplicatedStorage:WaitForChild("workspaceEvents").rockets.launch:FireServer()
end)

How may I execute this as a global event, while it is in a local script (If this is possible.)

All help appreciated!
