hi i keep getting the following error message from the following error message. why am i getting this message from the script below the table exists.

 

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/hmtcompa/public_html/testing/demo.php on line 6

SELECT * FROM tblcatdetails ORDER BY category ASC

 

<?
include("global/connection.php");
include("global/mail.class.php");
error_reporting(7);
$query_category = "SELECT * FROM tblcatdetails ORDER BY category ASC";
$category = mysql_query($query_category, $db) or die(mysql_error() ." ".$query_category);
$row_category = mysql_fetch_assoc($category);
header("Cache-Control: no-cache");
?>

[genericnumber1]

mysql_query($query_category, $db)

 

in this, $db is an invalid connection. Track this back to find out why, and if you are unable to, post the code so we can take a look.
