Ok maybe someone can see something im missing (its driving me in sane)
Help with Code Tags 
 
$query = mysql_query("UPDATE user SET meso='1' WHERE uid='$this->user'");
		$nrows = mysql_num_rows($query);
		$ret = mysql_query($query) or die(mysql_error());

this returns:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /Applications/MAMP/htdocs/worldjam/wjm.php on line 16

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1

what am I doing wrong?
Thanks in advanced
Tom
