         addhours_fun ( otcm.day6_hrs, otcm.day7_hrs) AS tothrs,Let me hep you format your code:
select   empm.empno,
         empm.firstname || ' ' || empm.surname as empname,
         otbm.empno,
         otbm.ceilingcode,
         to_char ( otbm.startdate, 'DD-MM-YYYY') as startdate,
         otcm.otceilinghrs,
         max (decode (otbd.weekday, 1, otbd.dayceilinghrs, null)) as day1_hrs,
         max (decode (otbd.weekday, 2, otbd.dayceilinghrs, null)) as day2_hrs,
         max (decode (otbd.weekday, 3, otbd.dayceilinghrs, null)) as day3_hrs,
         max (decode (otbd.weekday, 4, otbd.dayceilinghrs, null)) as day4_hrs,

         max (decode (otbd.weekday, 6, otbd.dayceilinghrs, null)) as day6_hrs,
         max (decode (otbd.weekday, 7, otbd.dayceilinghrs, null)) as day7_hrs,
         addhours_fun ( otcm.day6_hrs, otcm.day7_hrs) as tothrs,
