Hi Paolo, I think that you have two errors. The first is that AppendTo has a capital T The second is that you need to initialise rr outside the loops. It seems that rr={} inside the AppendTo function is applying the initialisation after the Append rr={}; For[a = 2, a < 6, a++, For[b = 2, b < 6, b++, AppendTo[rr, a^b]]] rr Nigel King On 20 Jan 2013, at 06:21, Paolo cachecho <paolocach at gmail.com> wrote: For[a = 2, a < 6, a++, For[b = 2, b < 6, b++, Appendto[rr = {}, a^b]]] rr
