Can someone look at this code snippet to find the error?

[marshill]

Im trying to create a nice little piece of code that will pull threads from my forums no matter where I put the page. (I dont want clientside javascript). Currently, this code isn't working, can someone give it a quick look and see where it might be wrong?

<?php  
$db_host = "localhost"; 
$db_name = "databasename"; 
$db_user = "username"; 
$db_pw = "dbpassword"; 

$forum_url = "http://www.mysite.com"; 
$limit = "5"; 
$postedcolor = "#404040"; 
$fontface = "arial,verdana,geneva"; 
$txtlimit = "50"; 
$num = "0"; 


mysql_connect($db_host, $db_user, $db_pw)  
OR die ("Cannot connect to your database");  
mysql_select_db($db_name) OR die("Cannot connect to your database");  

$tsql = mysql_query("SELECT threadid,title,postusername FROM thread ORDER BY threadid DESC LIMIT $limit"); 

while($tget=mysql_fetch_array($tsql)) 
{ 
$num = $num+1; 
$title = $tget['title']; 
$tid = $tget['threadid']; 
$poster = $tget['postusername']; 
echo "<strong>$num.</strong> <a href=\"$forum_url/showthread.php?t=$tid\">$title</a><br /><font color=\"$postedcolor\" face=\"$fontface\" size='1'><i>posted by $poster</i></font><br /><br />"; 
} 
?>
