URGENT NEED OF HELP

Hi, I'm a computer science student and a beginner in learning Oracle and PL/SQL.
I have a big (or a little?) problem:

I have written this piece of code

   SELECT COUNT(*) INTO contat FROM OCCUPAZIONE

        where tipo='s' AND A_ACCAD=accade 
          AND GIORNO=TO_NUMBER(giorn,'9') AND NOME_EVENTO=even 
          AND ORA_INIZIO=o_ini AND MINUTO_INIZIO=m_ini;

and the problem is that if the SELECT founds some data, then I receive the following message:

 Request Failed

 We were unable to process your request at this time.  Please try again later.

I don't know what to think anymore!!!!

Please Help me.
Thanks.
