Code block works in SQL Command Processor but not in application

Question

Hello forum,
Been struggling with this for a few days without success:
I have a form with a popup LOV called P6_POPUP, a file browse item called P6_BROWSE, a SUBMIT button, and a Process with the following code:
declare
q_image_id number;
begin
select host_family_photos_seq.nextval into q_image_id from dual;
insert into host_family_photos (image_id, file_object_id, image_name)
select q_image_id, id, filename
from htmldb_application_files where filename = :P6_BROWSE;
update host_family set image_id = q_image_id where family_name = :P6_POPUP;
end;
The Process Point is set to On Submit after Computations and Validations and When Button Pressed is set to the Submit button.
When I run the page the file is imported into HTMLDB_APPLICATION_FILES
but the insert and update do not occur.
The URL header after submitting is as follows:
http://127.0.0.1:8080/apex/f?p=115:1:480837828458787::NO:::&success_msg=Photo%20Imported%2FB87C5A54684B0DF005D09D0DFE6E98D6%2F
However if I run the above code in the APEX SQL Command window and supply the required variables it works every time - most confusing.
Not sure what to try from here.
thanks for your time,
Brett

Scott:
I always thought that the File Browse item maps to the NAME column in the view (below) and that is guaranteed to be unique. The NAME column seems to have a system-generated "F1234" id embedded in it (to guarantee uniqueness, I thought).
In other words, when we put a File Browse item on the page, submitting the page uploads the file into the HTMLDB_APPLICATION_FILES table and the way to access that record (to copy/move it into our own custom table) is by doing
from htmldb_application_files
where name = :P1_BROWSEThanks
