Lines not working, but no errors in output? (Filtering Enabled)

The following lines of code are snipped from the original script.

The code fires when a new player joins the game. It is located within a Server-Sided script.

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player
    local cash = Instance.new("NumberValue")
    cash.Name = "Cash"
    cash.Value = usercashpath
    cash.Parent = leaderstats

The problem is, the leaderstats folder is not created into the player.

I figured out the issue, i was using FindFirstChild(), instead of :WaitForChild for usercashpath value.
