The alias Interrest and MonthNos are temporary and cannot be used in single select statement, so use the query i gave you above.


Also teera, why dont you close the open items posted earlier which you think are already replied for you.

you can also do this if you don't want to rewrite the formulas.
SELECT *,(MonthNos*2-1)*Interrest As MiniPay
FROM
(SELECT balanceborow.wid, balanceborow.wname, balanceborow.amout,  CEILING(balanceborow.amout*.02) AS Interrest, balanceborow.DateBalance, balanceborow.amout, Round(DATEDIFF( NOW() , balanceborow.DateBalance)/30, 0) As MonthNos 
FROM balanceborow
WHERE balanceborow.wid ='$AccNo')
