Pulling my hair out!!!

[admin]

Ok...I've been working on this code for the past 3 hours. If anyone could help...that'd be great!

I keep getting this error when trying to submit a form from a browser:

Warning: Supplied argument is not a valid MySQL-Link resource in /usr/local/etc/apache_1.3.12/htdocs/test/eventsform.php on line 12
Insert failed!


Here is the PHP file that the form accesses:

<?PHP
$dbhost='localhost';
$dbusername='xx';
$dbuserpassword='xx';
$default_dbname='events';

$link_id=mysql_connect($dbhost, $dbusername, $dbuserpassword) or DIE("Unable to connect to Server!");

$db=mysql_select_db("events", $link_id) or DIE("Unable to select database!");

$query="INSERT INTO events VALUES(NULL, '$name','$date','$body')";
$result=mysql_query($query, $db) or DIE("Insert failed!");

?>

<h2> Event added! </h2>
