A Player Picker not working properly... Says stuff about nil value... Help?

local Players = game.Players:GetPlayers()
local TopHat = { }
fBeastSpawn = game.Workspace.Map1.MapData.BeastSpawns.fBeastSpawn
sBeastSpawn = game.Workspace.Map1.MapData.BeastSpawns.sBeastSpawn
BeastSpawns = {fBeastSpawn, sBeastSpawn}

table.insert(TopHat, Player)
for _, Player in pairs(Players) do
for i=1, Player.chancestats.RW.Value do 
TopHat[#TopHat + 1] = Player 
end
end

local Beast = TopHat[math.random(1, #TopHat)]
wait(30)

local scythe = game:service('ServerStorage'):findFirstChild('Scythe');
if scythe ~= nil then
scythe:clone().Parent = Beast:WaitForChild('Backpack');
game.Players.LocalPlayer.Backpack.scythe.Parent = game.Players.LocalPlayer.Character
end

local BHumanoid = Beast.Humanoid
BHumanoid.MaxHealth = "1000"
BHumanoid.Health = "1000"
BHumanoid.WalkSpeed = "20"

Beast.TeamColor = BrickColor.new("Really Black")

local Exp = Instance.new("SpecialMesh",Beast.Torso)
Exp.MeshType = Enum.MeshType.FileMesh
Exp.MeshId = "http://www.roblox.com/asset/?id=42579239"
Exp.TextureId = "http://www.roblox.com/asset/?id=42578558"
Exp.VertexColor = Color3.new(-90, -100, 47)
Exp.Scale = Vector3.new(10, 10, 10)

local CBSpawn = BeastSpawns[math.random(1, #BeastSpawns)]
Beast:MoveTo(CBSpawn.Position)
