Dear All,

I've a form that allow the user to enter information & save it.

in the form there is text_item called AMOUNT with multiable records.

I want when the user press SAVE button, a popup message shows the number of records enterd & total amount in all records.

EX:
AMOUNT
1000
200
3000

After clicking Save button a popup message shows ( you enterd 3 records & 4200 $ ) OK ? Cancel?
-------------

this my code in WHEN-BUTTON-PRESSED trigger

if :amount IS NOT NULL THEN

declare
cnt_record number := 1;
cnt_amount number :=:amount;

begin
go_item('amount');
first_record;

while :system.last_record = 'FALSE'
loop
cnt_record := cnt_record + 1;
cnt_amount :=cnt_amount + :amount;
next_record;
end loop;

message('There are ' || cnt_record || ' records and the total amount is'|| cnt_amount );
end;
END IF;
-----

BUT !! when I test the form nothing happend ...plzzzzzz need Help

Forms informs you about that by default (see status line at the bottom of the form), so - in my opinion, you don't have to do anything but point users to use what's already there.

Mentioning "save" button: which button is that? Did you create it, or is it placed in Forms built-in toolbar? If the latter, then this trigger won't do anything, that's true, because WHEN-BUTTON-PRESSED won't work with it. Whichever button it is, this code won't even save anything into the database (as it lacks COMMIT).

MESSAGE, as it is, displays information in previously mentioned status line. If you want a popup message, duplicate that MESSAGE command, i.e.

message('There are ' || cnt_record || ' records and the total amount is'|| cnt_amount );
message('There are ' || cnt_record || ' records and the total amount is'|| cnt_amount );

Alternatively, create an alert.

P.S. Forgot to mention: you don't have to loop through all records to count them; simply navigate to LAST_RECORD and :SYSTEM.CURSOR_RECORD will tell you which record it is.

What about setting the calculation property of the column?

Mr Nada_am,

Please create a alert and do not change any property in the property pallate.

In the WHEN-BUTTON-PRESSED trigger execute the following code.

if :amount IS NOT NULL THEN

declare 
cnt_record number := 1;
cnt_amount number :=:amount;
alrt varchar2(200);
alrt2 varchar2(300);


begin
go_item('amount');
first_record;

while :system.last_record = 'FALSE' 
loop
cnt_record := cnt_record + 1;
cnt_amount :=cnt_amount + :amount;
next_record;


alrt2:='There are ' || cnt_record || ' records and the total amount is'|| cnt_amount ;
end loop;
set_alert_property('ALERT1',ALERT_MESSAGE_TEXT,alrt2);
alrt:=show_alert('ALERT1');

end;
END IF;
