Subtract sum of two columns in two different tables and display balance for each row

Question

Hello Friends,
I have the below 5 tables
1. STUDENT (STUDENT_ID, NAME)
2. DEPARTMENT (DEPT_ID, NAME, CONTACT_PERSON, PHONE)
3. SECTION (SECTION_ID,SNAME,DEPT_ID,Acad_LEVEL,SHIFT,TIME,ROOM)
4. TUITION_BILL (Seq_No,  STUDENT_ID,  DEPT_ID,  Acad_Level,  SECTION_ID,  SEMESTER,  Acad_Year, BILL_DATE,  GROSS_AMT_DUE)
5. TUITION_PAYMENT (Seq_No,RECEIPT_NO,STUDENT_ID,DEPT_ID,Acad_Level,SECTION_ID,SEMESTER,Acad_Year,SCHOLARSHIP,PAYMENT_DATE,PAYMENT_AMT,REFERENCE,REMARKS)
I wrote the following query
SELECT T.Seq_No,T.STUDENT_ID,S.NAME As STUDENT_NAME,d.name As DEPT,T.Acad_Level,c.SNAME As SECTION,
T.SEMESTER,T.[Acad_Year],BILL_DATE,GROSS_AMT_DUE,
COALESCE(SUM(T.GROSS_AMT_DUE),0)-COALESCE(SUM(PAY.PAYMENT_AMT),0)- COALESCE(SUM(PAY.SCHOLARSHIP),0) As BALANCE
FROM TUITION_BILL T JOIN STUDENT S ON S.STUDENT_ID=T.STUDENT_ID join DEPARTMENT d on d.DEPT_ID=T.DEPT_ID
join SECTION c on c.SECTION_ID=T.SECTION_ID LEFT JOIN (SELECT DISTINCT STUDENT_ID,COALESCE(SUM(p.PAYMENT_AMT),0) As PAYMENT_AMT,
COALESCE(SUM(P.SCHOLARSHIP),0) As SCHOLARSHIP FROM TUITION_PAYMENT p GROUP BY p.STUDENT_ID) As PAY ON PAY.STUDENT_ID=T.STUDENT_ID
WHERE s.STUDENT_ID='138218' GROUP BY T.Seq_No,T.STUDENT_ID,S.NAME,d.NAME,T.[Acad_Level],c.SNAME,T.SEMESTER,
T.[Acad_Year],BILL_DATE,GROSS_AMT_DUE,PAYMENT_AMT,SCHOLARSHIP
The above query shows the below output
Seq_No
STUDENT_ID
STUDENT_NAME
DEPT
Acad_Level
SECTION
SEMESTER
Acad_Year
BILL_DATE
GROSS_AMT_DUE
BALANCE
1

There are two records in the TUITION_BILL table with different Semesters and bill dates for the specified student_id and there is only one record in the TUITION_PAYMENT table which is the semester one payment record. Semester two payment record
is not recorded yet and I want to display the balance like the following output instead of the above output.
Seq_No
STUDENT_ID
STUDENT_NAME
DEPT
Acad_Level
SECTION
SEMESTER
Acad_Year
BILL_DATE
GROSS_AMT_DUE
BALANCE
1

The above query is working fine but I'm facing only one problem with it which its showing 0 balance for both records instead of different balances like the above desired output.
Please help me in getting the desired result.
Any help would be appreciated.
Thanks in advance,
