23:26:29.906 - Workspace.Main:9: attempt to get length of global 'SMode' (a userdata value)

Can anyone help me figure out why it's giving me this error?

	Character.Torso.Anchored = false
	local SMode = OBS.GameMode.Easy
	local Next = math.random(1, #SMode)
	Next.Parent = game.Workspace
	Next.PrimaryPart.CFrame = game.Workspace.Start.CFrame * CFrame.new(0,0,12)
end

function UpdateGame()
	local Start = OBS:FindFirstChild("Start"):Clone()
	Start.Parent = game.Workspace
	Character.Torso.CFrame = Start.Spawn.CFrame * CFrame.new(0,5,0)
	local PGui = PlayingGui:Clone()
	PGui.Parent = player.PlayerGui
	local MGui = ModeGui:Clone()
	MGui.Parent = player.PlayerGui
	local Find = OBS.GameMode
	PMode = player.Stats.Mode
	PMode.Changed:connect(SpawnNext)
end
