For loops return Null (the same for Do loops) Table returns the required result Table[NIntegrate[ ref[\[Lambda], \[Theta], \[Phi], Pi/5, (2*Pi)/5], {\[Theta], 0, Pi}, {\[Phi], 0, 2*Pi}], {\[Lambda], 0, 10, 0.01}] best yehuda On 10/7/07, General <mammasis82 at hotmail.com> wrote: > > Hi, > > I have a function which I have numerically integrated in Mathematica.
