Can someone help with "attempt to index nil with SavedQualityLevel"?

It gives me the error "Attempt To Index Nil With SavedQualityLevel" and i just cant seem to find out why

local GameSettings = game:GetService("UserGameSettings")
local Valid = false


	for i = 1,50 do
		wait(1)
		if GameSettings.SavedQualityLevel == Enum.QualityLevel.Level08 or GameSettings.QualityLevel == Enum.QualityLevel.Level09 or GameSettings.QualityLevel == Enum.QualityLevel.Level10 then
			Valid = true
			print(Valid)
		elseif not GameSettings.SavedQualityLevel == Enum.QualityLevel.Level08 or not GameSettings.QualityLevel == Enum.QualityLevel.Level09 or not GameSettings.QualityLevel == Enum.QualityLevel.Level10  then
			Valid = false
			print(Valid)
		end
	end

I'm Trying to check if the SavedQualityLevel is 8 or above So if it is not too much to ask please help?
