Why my checkpoint system is just teleporting me to the stages?

I am trying to make an obby that uses checkpoints and saves the data, i have tested it with my friends but it only teleports me to the stage i left. Help please.

Server Script:

game.Players.PlayerAdded:Connect(function(Player)
Player.CharacterAdded:Connect(function(char)
		repeat wait() until Player.Character ~= nil
		if Stage.Value == 0 then return end
		local Checkpoint = game.Workspace:FindFirstChild(Stage.Value)
		if Checkpoint then
			char:MoveTo(game.Workspace[tostring(Stage.Value)].Position)
		end
	end)
end)

The checkpoints name are the same as of its stage. No errors.

Thanks. If you want more information ask.

Quite a stupid question.

game.Players.PlayerAdded:Connect(function(Player)
Player.CharacterAdded:Connect(function(char)
        repeat wait() until Player.Character ~= nil
        if Stage.Value == 0 then return end
        local Checkpoint = workspace:FindFirstChild("Stage")
        if Checkpoint then
            char:MoveTo(tonumber(Checkpoint.Value))
        end
    end)
end)

tell me if that works.

Fixed it, just saw another youtube video on how to make checkpoints and followed his instructions, here is the final result:

function Teleport(Char)
	local Player = game.Players:GetPlayerFromCharacter(Char)
	if Player ~= nil then
		repeat wait() until Char.HumanoidRootPart ~= nil
		local ls = Player.leaderstats
		local sl = game.Workspace:FindFirstChild(ls.Stage.Value)
		Char.HumanoidRootPart.CFrame = Char.HumanoidRootPart.CFrame + Vector3.new(0,3,0)
		wait()
		Char.HumanoidRootPart.CFrame = sl.CFrame + Vector3.new(0,3,0)
	end
	
end

game.Workspace.ChildAdded:Connect(Teleport)

However, anyone who answers why the old script didn't worked and this one yes, it will be marked as answer.
