"Learn How to Use Flash with PHP and mySQL" - Stuck! Please help!

I’m trying to link a MySQL database via php to my flash movie, whcih should display a list of pubs. I have a movie clip (which just consists of a dynamic text box with variable name ‘house’) which has these actions attached to it:
onClipEvent (load) {
loadVariables(“http://localhost/read.php”, this, “POST”);

My PHP file is called ‘read.php’ and has the following code (i’ve replaced the username/password with ???):

$type = $_POST[“type”];
$dbhost = “localhost”;
$dbname = “eldridge”;
$dbuname = “???”;
$dbpass = “???”;
mysql_connect($dbhost, $dbuname, $dbpass);
$connect = @mysql_connect($dbhost, $dbuname, $dbpass);
if (!$connect){
echo “&house=Server Error&”;
if (!@mysql_select_db($dbname)){
echo"&house=Database Error&";
$result = @mysql_query(“SELECT house FROM houses WHERE type=’$type’”);
if ($result && @mysql_num_rows($result) > 0){

while($row = mysql_fetch_array($result)){
$homes = $row[‘house’];
$return .= ‘’ . $homes . ‘<br>’;
print"&house=No Results&";

This doesn’t seem to work at all and i’m getting no results at all, could anyone suggest what i’ve done wrong or what i could do to try and fix it?

Thanks in advance for any help
