SQL statement ignored and missing opening parenthesis - oracle

Question

I get these errors during a creation of a trigger but I don't understand why
create or replace NONEDITIONABLE TRIGGER magazzino_bef_ins
BEFORE INSERT ON MAGAZZINO
FOR EACH ROW
DECLARE
tempcodice varchar2(8);
cacc char(3);
ogg int;
CURSOR cursore_disp IS
SELECT cacciatore, oggetto
FROM TABLE EDDY.disponibilita
WHERE ID_DISPONIBILITA = :NEW.disponibilità;
BEGIN
CURSOR cursore_disp IS
SELECT cacciatore, oggetto
FROM TABLE DISPONIBILITA
WHERE ID_DISPONIBILITA = :NEW.disponibilità;
open cursore_disp;
fetch cursore_disp into cacc,ogg;
temp:= pk_gestione_magazzino.genera_catalogo(cacc,ogg);
:new.codcatalogo:=temp;
END;
The errors are:
Error(5,9): PL/SQL: SQL Statement ignored
Errore(6,20): PL/SQL: ORA-00906: missing opening parenthesis
Errore(9,8): PLS-00103: encountered symbol "CURSORE_DISP" instead of one of the following: := . ( # % ;
I can't understand these errors, I'm just trying to take the values from a table in where the id inserted is equal in the other table.

Here's how. I created test environment which is kind of stupid, but it makes the following code work.
SQL> create table magazzino (disponibilita number, codcatalogo varchar2(8));
Table created.
SQL> create table disponibilita (cacciatore char(3), oggetto number, id_disponibilita number);
Table created.
SQL> create or replace package pk_gestione_magazzino as
2 function genera_catalogo (cacc number, ogg number) return varchar2;
3 end;
4 /
Package created.
SQL> create or replace package body pk_Gestione_magazzino as
2 function genera_catalogo (cacc number, ogg number) return varchar2 is
3 begin
4 return 'Little';
5 end;
6 end;
7 /
Package body created.
Trigger which causes you trouble: no need for a cursor; moreover, you have two of them (was it just a typo)? It looks as if you used it to avoid no data found error. If so, don't do it - it just makes confusion. Handle exceptions properly. By the way, you "forgot" to close the cursor.
SQL> create or replace trigger magazzino_bef_ins
2 before insert on magazzino
3 for each row
4 declare
5 cacc char(3);
6 ogg int;
7 begin
8 select cacciatore, oggetto
9 into cacc, ogg
10 from disponibilita
11 where id_disponibilita = :new.disponibilita;
12
13 :new.codcatalogo := pk_gestione_magazzino.genera_catalogo (cacc, ogg);
14 end;
15 /
Trigger created.
Testing:
SQL> insert into disponibilita values (1, 1, 1);
1 row created.
SQL> insert into magazzino (disponibilita) values (1);
1 row created.
SQL> select * From magazzino;
DISPONIBILITA CODCATAL
------------- --------
1 Little

Works, kind of.
