Passing value from MD form to bind variable in report

Question

I have an MD form, after I insert I want to redirect to a form and pass a value out of the detail section to the form to use as the value of it's bind variable. This works well on normal forms, but I cant seem to get it to work on the MD form. Below is an easy example and this doesnt work for me.
MD form master dept/detail emp, code under the save button:
doSave;
declare
l_empno integer;
l_url varchar2(2000);
begin
l_empno := p_session.get_value_as_NUMBER(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_EMPNO',
p_index => 1);
l_url := 'SCOTT.EMP_RPT.show?'| |
'p_arg_names=empno&p_arg_values='
| |l_empno;
portal30.wwa_app_module.set_target(l_url,'CALL');
end;
The form displays the empolyee information based on the value of empno from the MD form. The url looks like this http://hostname/pls/portal30/scott.emp_rpt.show?l_arg_names=empno&l_arg_values=
so no rows get returned because there is no value, if i fill it in with a empno it works, so i know the report works, it just isnt the get_value isnt grabbing the empno from the MD form.

I figured it out, the save button on a MD form, the doSave; clears out the form fields so do a get_value_as will not work b/c there is nothing there, you need to get the value before the doSave; the below code will work.
declare
l_empno number;
l_url varchar(2000);
begin
l_empno := p_session.get_value_as_NUMBER(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_EMPNO',
p_index => 1);
doSave;
l_url := 'scott.EMP_RPT.show?'| |
'p_arg_names=empno&p_arg_values='
| | l_empno;
portal30.wwa_app_module.set_target(l_url, 'CALL');
end;
