thanks for your reply
this is my query

SELECT Group.Group_ID, Group.Group_Name, Sum(MainTbloan.LoanAmount) AS SumOfLoanAmount, Sum(MainTblCredit.FixedSaving) AS SumOfFixedSaving
FROM (([Group] INNER JOIN Woman ON Group.Group_ID = Woman.Group_ID) INNER JOIN MainTblCredit ON Woman.Mem_ID = MainTblCredit.MemID)
INNER JOIN MainTbloan ON Woman.Mem_ID = MainTbloan.MemID
GROUP BY Group.Group_ID, Group.Group_Name
HAVING (((Group.Group_ID)=19)) OR (((Group.Group_ID)=20));

This is the result which is a wrong total for SumOfFixedSaving
Group_ID Group Name SumOfLoanAmount SumOfFixedSaving
19 Tawfiq 1359990 248090
20 Jawidan 119390 21450
Grand total 1479380 269540
