SQL row fetch based on other page items

Question

Hi ,
I am new to Application Express.
Please guide me .
I have a table with three keys.
Now I am displaying records in ther report part(page 33) of forms with report.
I have provided navigation on one of the primary keys.
One clicking on the key value it takes me to the form page(page 34) where the details of that speicific record are displayed. The page fetches teh details on the basis of automated row fetch using two primary keys as the condition for selecting the specific record from table.
Now since I want the record to be fetched on th basis of three primary keys instead of two(limitation) of Automated Row fetch . I had to create a sql process.
I wrote the following query but its not being able to fetch any data.
Displays no data found on navigating from the report page (33) to form page(34).
There seems to be something wrong with the query.
select
PROGRAM,SUB_PROG,DELIVERABLE,SOURCE,REC_COUNT,CREATE_BY,CREATE_DATE,
LAST_UPDATE_BY,LAST_UPDATE_DATE,BTORDIRECTOR,AOPTERRITORY,
FIELDSERVRGM
INTO
:P34_PROGRAM,:P34_SUB_PROG,:P34_DELIVERABLE,:P34_SOURCE,:P34_REC_COUNT,:P34_CREATE_BY,:P34_CREATE_DATE,:P34_LAST_UPDATE_BY,:P34_LAST_UPDATE_DATE,:P34_BTORDIRECTOR,:P34_AOPTERRITORY,:P34_FIELDSERVRGM
FROM CAP_NIMS_MANUAL
WHERE
PROGRAM=(:P34_PROGRAM) and
SUB_PROG=(:P34_SUB_PROG) AND
DELIVERABLE=(:P34_DELIVERABLE)AND
REC_COUNT=(:P34_REC_COUNT);

Hi,
Thanks for your suggestion.
all the four fields have value.
I have fixed the process point as new instance
while the query is as follows.
Now it displays the value of only the first three fields which are primary keys while it is not being able to fetch the value of other fields.
i.e Prog, Sub Prog, and Deliverable
select
REC_COUNT,CREATE_BY,CREATE_DATE,
LAST_UPDATE_BY,LAST_UPDATE_DATE,BTORDIRECTOR,AOPTERRITORY,
FIELDSERVRGM
INTO
:P34_REC_COUNT,:P34_CREATE_BY,:P34_CREATE_DATE,:P34_LAST_UPDATE_BY,:P34_LAST_UPDATE_DATE,:P34_BTORDIRECTOR,:P34_AOPTERRITORY,:P34_FIELDSERVRGM
FROM CAP_NIMS_MANUAL
WHERE
PROGRAM=(:P33_PROGRAM) and
SUB_PROG=(:P33_SUB_PROG) AND
DELIVERABLE=(:P33_DELIVERABLE) and
REC_COUNT=(:P33_REC_COUNT);
