        int enteredAmnt,paidAmount = 0;
        String billNo;

        enteredAmnt = OrderApplication.ENTERED_BILL_AMOUNT;

        Log.e("Prachi","Entered Amount" +enteredAmnt);

        if(enteredAmnt != 0){

            for(int j = 0 ; j < aBillArr.size() ; j ++){

                int pendingAmount = Integer.parseInt(aBillArr.get(j).getPendingAmnt());
              //  billNo = Integer.parseInt(items.getbillNo());

                billNo = aBillArr.get(j).getBillNo();

                if(enteredAmnt > pendingAmount){

                    enteredAmnt = enteredAmnt - pendingAmount ;
                    paidAmount = paidAmount + pendingAmount ;
                    pendingAmount = 0 ;
                    db.updateReceipt(billNo,pendingAmount,paidAmount);

                    viewHolder.textVpendingAmnt.setText(items.getPendingAmnt());

                    Log.e("Prachi","Bill No" +billNo);
                    Log.e("Prachi","Pending Amount" +pendingAmount);
                    Log.e("Prachi","Paid Amount" +paidAmount);

                }
                else if(enteredAmnt < pendingAmount){

                    enteredAmnt = enteredAmnt - pendingAmount ;
                    paidAmount = paidAmount + pendingAmount ;
                    pendingAmount = abs(pendingAmount - enteredAmnt) ;
                    db.updateReceipt(billNo,pendingAmount,paidAmount);

                    viewHolder.textVpendingAmnt.setText(items.getPendingAmnt());

                }
                else if( enteredAmnt == pendingAmount){

                    enteredAmnt = enteredAmnt - pendingAmount ;
                    paidAmount = paidAmount + pendingAmount ;
                    pendingAmount = 0;
                    db.updateReceipt(billNo,pendingAmount,paidAmount);

                    viewHolder.textVpendingAmnt.setText(items.getPendingAmnt());
