{
var val=form.state.options[form.state.options.selectedIndex].value;
self.location='homes.php?state=' + val;
}
function reload1(form)
{
var val=form.state.options[form.state.options.selectedIndex].value;

include'admin/configs/configs.php';
@$state=$_REQUEST['state'];
@$county=$_REQUEST['county'];
@$city=$_REQUEST['city'];

$quer2=mysql_query("SELECT DISTINCT state,id FROM states"); 

if($state){
$quer=mysql_query("SELECT DISTINCT * FROM county where state='$state'"); }

$quer3=mysql_query("SELECT DISTINCT * FROM cities where county='$county'"); 

echo "<form method=post name=f1 action='homes.php?state=$state&county=$county'>";


echo "<select name='state' onchange=\"reload(this.form)\"><option value=''>Select one</option>";
while($mbfh2 = mysql_fetch_array($quer2)) { 
if($mbfh2['state']==@$state){echo "<option selected value='$mbfh2[state]'>$mbfh2[state]</option>"."<BR>";}
else{echo "<option value='$mbfh2[state]'>$mbfh2[state]</option>";}
