Radio button options in Servlet

Question

I am trying to develop radio buttons in a servlet program. The program is supposed to update a database using the radio button options . I am having problem with the program compiling after I add radio buttons.
When compile the program, I receive an error message: " The local variable Level is never read"
please tell me what I am doing wrong in the following code:
private void sendUpdateForm(HttpServletRequest request, HttpServletResponse response)
         throws IOException {
            String ID = request.getParameter("ID");
              PrintWriter out = response.getWriter();
              out.println("<BR><H2>Update Form</H2>");
              out.println("<BR>Please edit the name.");
              out.println("<BR>");
              try {
                String sql = "SELECT Name_of_Officer, Title," +
                  " Level," +
                  "Multiply_View, " +
                  " FROM tDATA.users6" +
                  " WHERE ID=" + ID;
                Connection conn = DriverManager.getConnection(dbUrl);
                Statement s = conn.createStatement();
                ResultSet rs = s.executeQuery(sql);
                if (rs.next()) {
                   int Level = rs.getInt(1);
                  String Multiply_View = rs.getString(2);
                      out.println("<BR><FORM METHOD=POST ACTION=Resultpage>");
                  out.print("<INPUT TYPE=HIDDEN Name=ID VALUE=" +ID + ">");
                  out.println("<TABLE>");
                  out.println("<TR>");
                  out.println("<TD>Level</TD>");
                  out.print("<BR><INPUT TYPE=RADIO " +
                            "Name=Levels CHECKED VALUE=1>RC Manager" +
                         "<BR><INPUT TYPE=RADIO " +
                  "Name=Levels VALUE=2>Group Manager");
                out.println("></TD>");
                  out.println("</TR>");
                  out.println("<TD>Multiply View  </TD>");
                  out.print("<TD><INPUT TYPE=TEXT Name=Multiply_View");
                  out.print(" VALUE=\"" + (Multiply_View) + "\"");
                  out.println("></TD>");
                  out.println("</TR>");
                  out.println("<TR>");
                  out.println("<TD><INPUT TYPE=RESET></TD>");
                  out.println("<TD><INPUT TYPE=SUBMIT></TD>");
                  out.println("</TR>");
                  out.println("</TABLE>");
                  out.println("</FORM>");
                s.close();
                conn.close();
              catch (SQLException e) {
                out.println(e.toString());
              catch (Exception e) {
                out.println(e.toString());
       void updateRecord(HttpServletRequest request,   HttpServletResponse response)
         throws IOException {
         String ID = request.getParameter("ID");
         int Level = Integer.parseInt(request.getParameter("Levels"));
         String Multiply_View = request.getParameter(("Multiply_View"));
         PrintWriter out = response.getWriter();
         try {
           String sql = "UPDATE tDATA.users6" +
             " SET Level ='" + (Level) + "'" +
           " Multiply_View='" + fixSqlFieldValue(Multiply_View) + "'" +
          " WHERE ID=" + ID;
           Connection con = DriverManager.getConnection(dbUrl);
           Statement s = con.createStatement();
           int i = s.executeUpdate(sql);
           if (i==1)
             out.println("Record updated");
           else
             out.println("Error updating record");
           s.close();
           con.close();
         catch (SQLException e) {
           out.println(e.toString());
         catch (Exception e) {
           out.println(e.toString());

When compile the program, I receive an error message:
" The local variable Level is never read"
if (rs.next()) { // begin if then block scope
                        // ** Level delcared as local variable of type int
                   int Level = rs.getInt(1); // ** does this get used ???
                  String Multiply_View = rs.getString(2);
                      out.println("<BR><FORM METHOD=POST ACTION=Resultpage>");
                  out.print("<INPUT TYPE=HIDDEN Name=ID VALUE=" +ID + ">");
                  out.println("<TABLE>");
                  out.println("<TR>");
                  out.println("<TD>Level</TD>");
                  out.print("<BR><INPUT TYPE=RADIO " +
                            "Name=Levels CHECKED VALUE=1>RC Manager" +
                         "<BR><INPUT TYPE=RADIO " +
                  "Name=Levels VALUE=2>Group Manager");
                out.println("></TD>");
                  out.println("</TR>");
                  out.println("<TD>Multiply View  </TD>");
                  out.print("<TD><INPUT TYPE=TEXT Name=Multiply_View");
                  out.print(" VALUE=\"" + (Multiply_View) + "\"");
                  out.println("></TD>");
                  out.println("</TR>");
                  out.println("<TR>");
                  out.println("<TD><INPUT TYPE=RESET></TD>");
                  out.println("<TD><INPUT TYPE=SUBMIT></TD>");
                  out.println("</TR>");
                  out.println("</TABLE>");
                  out.println("</FORM>");
}// **end if then block scopewas Level intended to be a local variable ?
