SELECT statement throwing error in Pro*C

Question

Hi All,
I have a Pro*C report that I am creating and the selmacro in the report has a SQL statement like
EXEC SQL DECLARE cursor_000 CURSOR FOR
SELECT (select 'Y' from dual)
FROM spriden
WHERE spriden_change_ind IS NULL;
Now this throws me an error saying :
Syntax error at line 538, column 16, file tzrages.pc:
Error at line 538, column 16 in file tzrages.pc
SELECT (select 'Y' from dual)
...............1
PCC-S-02201, Encountered the symbol "'Y'" when expecting one of the following:
( ) * + - / . @ | at, day, hour, minute, month, second, year,
Syntax error at line 1954, column 16, file tzrages.pc:
Error at line 1954, column 16 in file tzrages.pc
FROM DUAL;
My Observation is that when I put a "select" statement in the select clause of the SQL, it throws the error. However if I write the query with out the "SELECT" in the select clause, it works just fine.
Any clues on this. I need to have multiple "Select" statements in the SELECT clause, and cannot do without it.

Thanks Satrap and Billy for replying to the post. Appreciate it.
What the query actually looks like is
SELECT college_name
,college_location
,student_category
,sum(30_day_balance)
,sum(60_day_balance)
,sum(90_day_balance)
FROM ( SELECT college_name
,college_location
, NVL ( (SELECT DECODE (substr(A.company_id,1,1)
,'V','Bad Debt'
,'D','Active SAC'
FROM company_table A
,collections_table C
WHERE C.student_id = B.student_id
AND C.collector_id = A.collector_id
), 'Active'
) STUDENT_CATEGORY
, ( SELECT NVL ( SUM ( D.balance),0)
FROM balance_table D
WHERE D.balance_date BETWEEN to_date(:report_run_date) - 30 AND to_date (:report_run_date)
AND D.collection_code = :collection_code
AND D.student_id = B.student_id
) 30_DAY_BALANCE
, ( SELECT NVL ( SUM ( D.balance),0)
FROM balance_table D
     WHERE D.balance_date BETWEEN to_date(:report_run_date) - 60 AND ( to_date (:report_run_date) - 30 + 1)
AND D.collection_code = :collection_code
     AND D.student_id = B.student_id
     ) 60_DAY_BALANCE
     , ( SELECT NVL ( SUM ( D.balance),0)
FROM balance_table D
     WHERE D.balance_date BETWEEN to_date(:report_run_date) - 90 AND ( to_date (:report_run_date) - 60 + 1)
AND D.collection_code = :collection_code
     AND D.student_id = B.student_id
     ) 90_DAY_BALANCE
     FROM student_table B
     WHERE B.student_id IN ( SELECT E.student_id
     FROM collections_table E
     WHERE E.collection_code = :collection_code
     GROUP BY E.student_id
     HAVIN SUM(E.balance) BETWEEN :min_balance AND :max_balance
GROUP BY college_name,college_location,student_category
Please note that anything with a ':' as a prefix (:collection_code,:max_balance) is a parameter for the Query
When I run the query in toad, it works fine, but when I compile it in Pro*C it throws an error as mentioned in the previous post.
