include("../dbcon.php");
$dbcon1=new Dbcon();
$host=$dbcon1->host;

$db=$dbcon1->db;
mysql_connect($host,$user,$pass1) or die("could not connect:".mysql_error());
mysql_select_db($db);
$query="select UserName,Password FROM user where UserName='$divname' and Password='$pass'";
$result = mysql_query($query);
if($row = mysql_fetch_array($result,MYSQL_ASSOC))

$res = mysql_query("SELECT distinct untcode FROM div_gp where division='$division'")or die("Invalid query: " . mysql_query());
echo '<select class="style23" id="unt" name="unt" onchange="sel()">';
echo '<option value="">Select..</option>';
while ($row = mysql_fetch_array($res))
{
$va1 = $row['untcode'];
if(isset($_POST['unt']) )
{
if($va1==$_POST['unt'])
{
echo "<option value='$va1' selected>$va1</option>";
}
else
