$_server[php_self]

hi all i'm having issues with this returned function. I can get it to
delete a database but i really want it to grab the stateselect
extention and grab all the cities related to that state. I wanted to
contain this on one page instead of going over multiple pages which i
can do. Sorry if this doesn't make much sense i'm a newbie.. below is
the code. the isset($_get is where i have the issues. any help would
be appreciated.

<?php

$dbcnx = @mysql_connect('localhost', 'root', '');
if (!$dbcnx) {
die( '<p>Unable to connect to the ' .
'database server at this time.</p>' );
}
// Select the hotel database
if (! @mysql_select_db('uniguest') ) {
die( '<p>Unable to locate the Hotel List ' .
'database at this time.</p>' );
}

$result = @mysql_query('SELECT DISTINCT state FROM hotelList ORDER by
state');
if (!$result) {
die('<p>Error performing query: ' .
mysql_error() . '</p>');
}
while ( $row = mysql_fetch_array($result) ) {
echo(' | <a href="' . $_SERVER['PHP_SELF'] . '?stateSelect=' .
$row['state'] . '">' . $row['state'] . '</a>');
}


// Select the hotel database
if (! @mysql_select_db('uniguest') ) {
die( '<p>Unable to locate the Hotel List ' .
'database at this time.</p>' );
}

if (isset($_GET['stateSelect'])) {
$state2 = $_GET['stateSelect'];
$query = mysql_query("SELECT * FROM hotelList WHERE state='$state2'
ORDER by name")
or die (mysql_error());
$name = $row['name'];
echo($name);
} else {
echo('<p>Error: ' .
mysql_error() . '</p>');
}


?>
