[MySQL][PHP] problem z zapytaniem Opcje

[jjarkus]

Dręczy mnie pewien problem z moim kodem (IMG:style_emoticons/default/blinksmiley.gif)
Mianowicie tworzę sobie taką małą grę i problem jest następujący:
Podczas rejestracji nowego użytkownika wyskakuje taki błąd:

Kod

         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43
         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43
         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43

Skorzystałem też z

[PHP] pobierz, plaintext 
 echo mysql_error();
[PHP] pobierz, plaintext 

i pokazał taki komunikat:

Kod

         Something is wrong in your syntax obok 'SELECT id FROM stats WHERE display_name = 'mag' OR short_name = ' w linii 1

Wychodzi na to, że chyba wykonanie zapytania się nie powiodło.
W czym może tkwić błąd?
