How do I reference items in a report region

Question

I've created a report. You can view the region attributes at http://i3.tinypic.com/wcn59h.jpg.
I've changed the "Display As" attribute of one of the items (QUAN_ID) to 'Select List (query based LOV)'. I've set the "LOV Query" attribute on this item to the following.
select quan.answer_txt
, quan.id
from vug_question_answers quan
, vug_survey_questions suqu
where suqu.id = quan.suqu_id
and suqu.surv_id = :p33_surv_id
--and    suqu.id = :suqu_id
order by quan.question_answer_seq_no
The purpose of this LOV is to return QUESTION_ANSWERS that have a foreign key to the SURVEY_QUESTIONS record identified by the sufu_id. The bind-variable ":p33_surv_id" is a page item. I THOUGHT the bind-variable ":suqu_id" (referenced in the commented-out line) would be the name of a column item in my report region. However, the LOV doesn't return correct values if I uncomment the line containing :SUQU_ID.
How do I determine the name of the report region column item so that I can reference it within the LOV of another item in the same region?
Thanks,

Ivo,
That's it!
My original tabular form query read as follows.
select rean.id,
rean.resp_id,
suqu.surv_id,
suqu.question_txt,
quan.suqu_id,
rean.quan_id, --this is the column I was adding an LOV to
rean.entered_by,
rean.entered_on,
rean.updated_by,
rean.updated_on
from vug_respondent_answers rean
, vug_question_answers quan
, vug_survey_questions suqu
where rean.resp_id = :p33_resp_id
and quan.id = rean.quan_id
and suqu.id = quan.suqu_id
and suqu.surv_id = :p33_surv_id
I've changed it to the following.
select rean.id,
rean.resp_id,
suqu.surv_id,
suqu.question_txt,
quan.suqu_id,
htmldb_item.select_list_from_query
( 6
, rean.quan_id
, 'select quan.answer_txt, quan.id from vug_question_answers quan, vug_survey_questions suqu where suqu.id = quan.suqu_id and suqu.surv_id = :p33_surv_id and suqu.id = '|| suqu.id ||' order by quan.question_answer_seq_no') quan_id,
rean.entered_by,
rean.entered_on,
rean.updated_by,
rean.updated_on
from vug_respondent_answers rean
, vug_question_answers quan
, vug_survey_questions suqu
where rean.resp_id = :p33_resp_id
and quan.id = rean.quan_id
and suqu.id = quan.suqu_id
and suqu.surv_id = :p33_surv_id
