Scope of variales? confusing and very frustrating problem....please help?

Question

Below is my entire program (a simple pl/sql stored procedure) and for some reason the variable newpay is not appearing in SQL*Plus. Have have turned serveroutput on and have checked that the variable otpay contains values, it's just newpay doesn't seemed to want to print to screen. Is this something to do with varaible scope within cursor loops or something? Thanks a lot for your help.
CREATE OR REPLACE PROCEDURE lab5d (pp_fname varchar2, pp_lname varchar2, pp_month varchar2) AS
          TYPE ot_rec_type is RECORD
               fname          emptrig.fname%type,
               lname          emptrig.lname%type,
     otime_rate     emptrig.otime_rate%type,
               hours          overtime_sessions.hours%type,
               o_date          overtime_sessions.o_date%type
          TYPE cur_type is REF CURSOR;
     c1          cur_type;
     firstdate     date;
     lastdate     date;
     otpay          number;
     newpay          number;          
     ot_rec          ot_rec_type;
BEGIN
     firstdate := TO_DATE('01' || pp_month || '2002', 'DD-MON-YYYY');
     lastdate := LAST_DAY(firstdate);
     open c1 for     SELECT fname, lname, otime_rate, hours, o_date
               FROM     emptrig, overtime_sessions
               WHERE     etrigot_id = emptrig_id AND
                    fname = pp_fname AND
                    lname = pp_lname AND
                    o_date >= firstdate AND o_date <= lastdate;
     LOOP
          fetch c1 into ot_rec;
          exit when c1%notfound;
          otpay := ot_rec.hours * ot_rec.otime_rate;
          newpay := otpay + newpay;
     END LOOP;
          dbms_output.put_line(newpay); -- this line does not print but otpay contains values
END;

Michael,
You already asked this question Re: Oracle EM 10g - Running an OS Command and you were given a (in my opinion) correct answer. If you don't agree with the answer, or if you have tested it and it did not work, then post a reply to that message.
It is very frustrating for people who put in their time and effort to answer questions, to see the same question just being asked again by the same person, without receiving any feedback from the poster why his / her answer was neglected.
Maybe I am reacting to strong, but then again it still early in the morning and I haven't had my coffee yet.
