                // TODO Auto-generated method stub
                if (s.toString().trim().length() > 0) {
                    int rentValue = Integer.parseInt(s.toString()
                            .replaceAll(",", ""));
                    StringBuffer rentVal = new StringBuffer();
                    if (rentValue > 10000000) {
                        s.clear();
                        s.append("10,000,000");

                        if (s.length() == 4) {
                            char x[] = s.toString().toCharArray();

                            char y[] = new char[x.length + 1];
                            for (int z = 0; z < y.length; z++) {

                                if (z == 1) {
                                    y[1] = ',';

                                } else {
                                    if (z == 0)

                                rentVal = rentVal.append(y[z]);
                            }

                            s.clear();
