Error fetching from DB, but not sure what's wrong

I'm getting an error trying to fetch data from my database, but I'm not sure where. There error comes from the 2nd line, I think. As the code is, I get a blank page, and if I remove the 2nd or die it displays the page but won't echo anything from the DB. It's connected to the DB no problem. I've tried both mysql_fetch_array and mysql_fetch_assoc.

If it matters, PHP version is 5.2 and MYSQL is 5.5.23

Any help, or at least a point in the right direction, would be greatly appreciated.

$stats_get = mysql_query("SELECT * FROM stats WHERE id ='.#_SESSION[uid].'") or die(mysql_error());
$stats = mysql_fetch_array($stats_get) or die(mysql_error());
