Cannot retrieve into text area!!

Question

please urgent....
To make a text area that take text from the user in the dynamic page using the PL\SQL.i write this code:
<oracle>
declare
text varchar2(500);
begin
htp.formtextarea('textareaname',10,50,null,null);
text:= htf.formtextarea('textareaname',10,50,null,null);
end;
</oracle>
and it work well. but i wish to display a text in it to the user. That is to say when the user run the dynamic page the textarea appear containg this text, and the text i want to display is stored in the database. How can i do that, how to retrieve text from the database into the text area???
please answer me quickly.

Answer 1

This is my pl/sql code:
DECLARE
V_USER VARCHAR2(25);
BEGIN
V_USER:=v('APP_USER');
IF (:P8_COMMENT IS NOT NULL)
THEN
INSERT INTO COMMENTS(COMMENT,COMM_DATE,COMM_USER,REQUEST_ID)
VALUES (:P8_COMMENT,SYSDATE,V_USER,:P8_ID_REQUEST);
END IF;
END;
So, when I enter text into item :P8_COMMENT, and press my update button, it's like I haven't entered anything.
Thank you.
