Question

i have 3 data blocks in a form
one is Master and the other is Detail and in Detail block a buttons on which when i click another block against parameters of that test is shown
user enter value 1 and value 2 then in third column avg is calculated now i want to use a loop on detail block in which i want to populate that average which is calculated in that parameter block
i know the situation is complex to understand but plz help
thanks

Answer 1

this is detail block
sno testcode result button
1 10
2 20
3 30
now when i click on button to calculate the result
the parameter defined in a table against test 10 appears like this
parameter_id value1 value2 Avg (value1 and value2)
IBP 2 2 2
R10 3 3 3 Save button
Now the code under save button is
DECLARE
No_Rec number;
BEGIN
go_block('detail');
No_Rec:=:System.Cursor_Record;
First_Record;
          FOR I in 1..No_Rec loop
     If :parameter1.parameter_id = 'IBP' and :detail.test_code='10' then
:detail.result_value:=:avg;
end if;
if :parameter1.parameter_id = 'R10' and :detail.test_code='20' then
:detail.result_value:=:avg;
end if;
Next_Record;
End Loop;
end;
but it only returns one value not all in detail block and i have to check 7 conditions and have to populate 7 values from Parameter Block into detail
Thanks
