Answer 1

this is not related to FORMS at all......
1) create a database function which take grade parameter and return the total weightage.
2) use it on when-validate-item trigger to validate
create or replace function get_grade_weightage(p_grade varchar2)
return number
is
v_grade number;
begin
  select sum(Weightage)
   into v_weightage
  from mytable
where grade = p_grade;
exception when no_data_found then
   return 0;
end;
select get_grade_weightage(:grade)  into v_weigtage from dual;
if :current_weigth < v_weightage then
    -- do something
else
  --do something
end if;Hope it helps
plz mark the answer as correct or helpful if it is
