I'm trying to make the time and music change, it doesn't work. why? :/ [closed]

local Day = script.Parent:FindFirstChild("Day")
local Night = script.Parent:FindFirstChild("Night")
local Time = script.Parent:FindFirstChild("NewTime")
lcoal ct = game.Lighting.ClockTime

while true do   
    Day.Playing = false
    Time.Playing = true
    Time.Looped = false
    Night.Playing = true 
        ct = 12
    print("time changed")
wait(10)
    Day.Playing = true
    Time.Playing = false
    Time.Looped = false
    Night.Playing = false
        ct = 4
    print("time changed")
wait(60)
end
