Answer 1

Thanks you to fthiella,DeadZone,Beth and Thorsten Kettner who give me a right direction. Since trying many day using yours solution directly on MS Access IDE finally I found a trick. I need to thanks you very much to solving my problem. The trick is :-

A) IF RECORD IS EMPTY or EXIST by SELECTION then using (Select Nz(MAX(m.amount),'NOT PAID') as PAYFEB.

All kind solutions like LEFT JOIN or Direct SUBQUERIES are working actually. But I more prefer SUBQUERIES because more organize and I can see if any syntax or field are not register.

Lastly, without yours support I cannot get this answer of this matter. Thanks you very much guys.
