Mysql + redirect

Hvad er der galt her:

<?php

$dom = $_SERVER['HTTP_HOST'];
$MyArray = explode(".",$dom);
$domain = $MyArray[1] & "." & $MyArray[2];

$conn = mysql_connect("localhost", "xxx", "xxx");
mysql_select_db("db");
$result = mysql_query("SELECT * FROM subdomain where sub = '$dom'");
$row = mysql_fetch_array($result);


if(mysql_num_rows($result) == 0)
{
  echo('<META HTTP-EQUIV="refresh" CONTENT="0;url=http://www.'$domain'">');
}
else
{
    echo('<title>'$row['title']'</title>');
    echo('<frameset rows="0,100%" frameborder="NO" border="0" framespacing="0">');
    echo('<frame src="" name="topFrame" scrolling="NO" noresize>');
    echo('<frame src="http://www.'$row['domain']'/'$row['folder']'/" name="mainFrame">');
    echo('</frameset>'):
}


?>


Fordi det virker ikke.. Få bare en blank side...
