I can read Urdu and from what I can make out in images of the note, the Urdu text is fine. The font could have been better. The orthographic sign that makes the H in 'hazaar' is correct; the 'be' nuqta is a different shape. There should have been a hair-width's space after the 'dal' in 'do', but it is easily readable as 'dal' and not 'lam' as some people are claiming.
