Mysql Error

I keep getting this error

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in userstats.php on line 9

this is the code

Code:
$totallinks = mysql_query("select * from links where by = '$logged[username]'");
$totallinks = mysql_num_rows($totallinks);


The sql table is links and the field in it is by

I want it to find how many $logged[username] links has posted.

I tryed and tryed again for a long time and can't get thi to work

First make sure it IS valid resource-maybe something wrong with syntax?
$totallinks = mysql_query("select * from links where by = '$logged[username]'");
echo(mysql_error());
$totallinks = mysql_num_rows($totallinks);

BTW,shouldn't query be like this?
$totallinks = mysql_query("SELECT * FROM `links` where `by` = ".$logged[username]);

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 'by = 'Leo'' at line 1

try using
Code:
$totallinks = mysql_query("SELECT * FROM `links` WHERE `by` = '".$logged[username]."'");

with that it displays

Resource id #10

Also use the mysql_count_rows too of course.
But better (more effective) would be:

$totallinks = mysql_query("SELECT COUNT(1) FROM `links` WHERE `by` = '".$logged[username]."'");
$totallinks = mysql_fetch_row($totallinks);
$totallinks = $totallinks[0];
