why wont the variable change?

I am making a entermession and the varible for the entermession wont change.

game.Players.PlayerAdded:Connect(function(player)
	
while true do
	wait()
if game.ServerScriptService.System.Action.Value == 1 then
		game.ServerScriptService.System.works.Value = false
		game.ServerScriptService.System.Action.Value = 0
		local time = 20
		while time >= 0 do
			
			print("Entermession: "..time)
			player.PlayerGui.wordy.TextLabel.Visible = true
			player.PlayerGui.wordy.TextLabel.Text = "Entermession: "..time
			local time = time - 1 -- I feel like it is here but this code has no error.
			wait(1)
			
		end
		while time == -1 do
		
			player.ServerScriptService.System.works.Value = true
			local time = false
			player.PlayerGui.wordy.TextLabel.Visible = false

		end
end
	end	
	end)
