Displaying a field value from PL/SQL

Question

I'm working on a master detail form. In the detail section, I have added a button beside one of the fields. On the click of this button, I want to use a foreign key value from the current record, and get the description field from another table. I'm able to get the value from the form by use of p_sesion.get_value_as_NUMBER. I then perform the select statement to retrieve the description from another table. I would like to display this value to the user. Any ideas as to how I can do this?

Bala,
Just an update to let you know what we've tried up to this point:
We have created 3 functions:
1) Set_Occup_Desc - this sets the Occupation Description.
2) Get_Occup_Desc - this retrieves the Occupation Description.
3) Clr_Occup_Desc - this clears the Occupation Description.
On the click of the button, I have the following code:
declare
my_occup_desc varchar2(525);
my_occup_key number;
my_return_val boolean;
begin
my_occup_key := p_session.get_value_as_NUMBER(p_block_name => 'DETAIL_BLOCK', p_attribute_name => 'A_OCCUP_KEY', p_index => 1);
select occup_desc into my_occup_desc from wsoccup where occup_key = my_occup_key;
my_return_val := wsurv_util.set_occup_desc(my_occup_desc);
end;
In the After Displaying Form section, I have the following code:
htp.p(wsurv_util.get_occup_desc());
This doesn't display anything on the page, and I think that it's because multiple oracle sessions are being used within the one portal session, and the value of the variable is being lost.
Any ideas on a work around for this one?
