Not able to get the value from type defined in other progarm

Question

Hi All,
I have a create a type in one package spec(Globally), now i am using the same type in another package.Simply i am calling the first package and try to store the value in Type and use the same type in second package.
But i am not able get the value
Type declaration
Declared in package Spec
TYPE t_aa_derive_tbl_type IS TABLE OF xxxx%ROWTYPE;
   t_aa_derive t_aa_derive_tbl_type;
Package 1
Package1. PROCEDURE name(
some parameters);
is
Cursor
c1 is Select * from dual;
begin
      OPEN c_aa_derive;
        FETCH c_aa_derive
        BULK COLLECT INTO t_aa_derive;
        CLOSE c_aa_derive;
     END get_aa_derive;
In My second package
I am calling
Package1. PROCEDURE name(
some parameters);
and then i am trying to
for i in 1 .. package1.t_aa_derive.COUNT
  LOOP
end loop;
I am not able entered the loop for some reason.
Could some one guide me if anything i missed.
Cheers,
San

Why?
1. Why aren't you just using SQL to do the work?
2. Why don't you just open a CURSOR and pass that instead?
BULK COLLECT INTO t_aa_derive; 
3. Why aren't you using a LIMIT clause? Are you sure that only a very small number of rows will be queried?
4. Why aren't you using a PIPELINED function instead of passing a collection?
Using collections with potentially unlimited numbers of rows is not scalable. Also, using collections can be more difficult for 'data consumers' to work with than if you just use a CURSOR or PIPELINED function.
Make sure you are using the proper architecture so that your code is both modular, scalable and easy to use.
