Hi Claus,

just a short  answer ;),

Check  'st2' variable for zero value. It is possible,  that line

histos[i].ptr->GetHisto()->GetListOfFunctions()->FindObject("stats");

doesn't find object with the name "stats".

                            Best regards,
                                            Stanislav.
