Time script is working but server storage thing is not?

Here is my code

-- day length is minutes
local dayLength = 5

local cycleTime = dayLength*60
local minutesInADay = 24*60

local lighting = game:GetService("Lighting")

local startTime = tick() - (lighting:getMinutesAfterMidnight() / minutesInADay)*cycleTime
local endTime = startTime + cycleTime

local timeRatio = minutesInADay / cycleTime


if dayLength == 0 then
	dayLength = 1
end

repeat
	local currentTime = tick()
	
	if currentTime > endTime then
		startTime = endTime
		endTime = startTime + cycleTime
	end
		
	lighting:setMinutesAfterMidnight((currentTime - startTime)*timeRatio)
	wait(1/15)
until false

while true do
	wait(197)
	    game.ServerStorage.Night.Parent = workspace
		wait(1)
		game.ServerStorage.Gun.Parent = game.StarterPack
		wait(1)
		game.ServerStorage.NightSky.Parent = game.Lighting
		wait()
		game.Lighting.DaySky.parent = Game.ServerStorage
		wait()
		game.Workspace.Day.Parent = Game.ServerStorage
	end
while true do
	wait(236)
		game.ServerStorage.Day.Parent = workspace
		wait(1)
		game.ServerStorage.DaySky.Parent = game.Lighting
		game.ServerStorage.Night.Parent = workspace
		wait(1)
		game.ServerStorage.Gun.Parent = game.StarterPack
		wait(1)
		game.ServerStorage.NightSky.Parent = game.Lighting
		game.Workspace.Night.Parent = Game.ServerStorage.Night
		wait()
		game.Lighting.NightSky.Parent = Game.ServerStorage
		game.StarterPack.Gun.Parent = Game.ServerStorage
end
