Im making obby and i have problem with this script. Do you guys know how to fix this?

game.Players.PlayerAdded:Connect(function(plr)
    local stage = plr:WaitForChild("leaderstats").Stage -- I assume your stage capitalization is wrong. Consider changing the S to capital letter.
    plr.CharacterAdded:connect(function(char) 
    repeat 
        wait() 
    until plr.Character ~= nil 
    wait() 
    local Checkpoint = game.Workspace.Stages:FindFirstChild(stage.Value)
    char:FindFirstChild("HumanoidRootPart").CFrame = CFrame.new(Checkpoint.Position +Vector3.new(0,5,0), Checkpoint.Position) char:FindFirstChild("HumanoidRootPart").Orientation = Vector3.new(0,0,0) 
    wait() 
    end) 
end)
