My script is not working even though there are no errors. Any help?

The lighting properties are set to 11:59:57 but this script is not working. HELP!! here is the script-

if game.Lighting.TimeOfDay == "12:00:00" then
    script.Parent.Transparency = 0.5
wait(0.2)
Transparency = 0.5
wait(5)
script.Parent.CanCollide = false
wait(0.2)
CanCollide = false

if CanCollide == false then
    print("CanCollide has been set to false.")
end

if Transparency == 0.5 then 
    print("The baseplate is now transparent.")
end
end
