I'm trying to make a spawn script and it WON'T move the part?!

I'm just trying to spawn the character at a cylinder and this is the code on the server:

game.Players.PlayerAdded:Connect(function(player)

    player.CharacterAdded:Connect(function(char)

        local humanoidRootPart = char:WaitForChild("HumanoidRootPart")
        local area = game.Workspace:WaitForChild("GameContent")
        local mainArea = area:WaitForChild("WaitingArea")

        humanoidRootPart.CFrame = CFrame.new(mainArea:WaitForChild("Spawn").Position)
    end)
end)
