function newsletter()
{

if((isset($_GET['action']))&($action=="add")) { ?>

The email adding process has been completed.

<?php } 

if((isset($_GET['action']))&($action=="remove")) { ?>
The email removal process has been completed.
<?php }}

mysql_free_result($scl);
?>

The function retrieve_cats($cat) should display a list of every record in the database but it is giving me an error message of "Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/whizzell/public_html/nath/inc/functions.php on line 100"

I don't know where i'm going wrong. I had this error earlier today with the same error but somehow fixed it. Can't find a solution this time.

I'm calling the function with <?php $cat = 1; retrieve_cats($cat);?>

Thanks in advance.

Try replacing the retrieve_cats function with the following:

function retrieve_cats($cat)
{ global $scl;
	while ($row_sub_cat_list = mysql_fetch_assoc($scl))
	{  
	echo $row_sub_cat_list['name'].'<br />';
	}
}
