set @fInstmount=(select fInstmount from tblChitInstalments where iChitId=@iChitId and iInstNo=(select max(iInstNo) from tblDCPayment where ichitId=@iChitId))   
declare @dInstDate datetime
set @dInstDate=(select dInstDate from tblChitInstalments where iChitId=@iChitId and iInstNo=(select max(iInstNo) from tblDCPayment where ichitId=@iChitId))
declare @Balance float
set @Balance=(select fInstmount-fPaidAmount from tblDCPayment where iChitId=@iChitId and iRegId=@iRegId)
