Need HELP to pass results from procedure

Question

Hey Gurus,
I need your help. I got a package (test) and inside the package two procedures (step1, step2). Now I want to pass the results from the procedure step1 (stat_rec.lev, stat_rec.chi_sq, stat_rec.chi_sig) to the other procedure step2 and make a select with where-clause. How can I manage this?? Got someone a idea??
Here my package:
CREATE OR REPLACE PACKAGE test1
AS
PROCEDURE step1(table_in IN VARCHAR2, column1 IN VARCHAR2,column2 IN VARCHAR2);
TYPE stat_tab_rec IS RECORD(lev NUMBER, chi_sq NUMBER, chi_sig NUMBER, rank NUMBER);
stat_rec stat_tab_rec;
PROCEDURE step2(table_in IN VARCHAR2, column1 IN VARCHAR2,column2 IN VARCHAR2);
END test1;
Thanks for your help!!
CREATE OR REPLACE PACKAGE BODY test1
AS
PROCEDURE step1(table_in IN VARCHAR2, column1 IN VARCHAR2,column2 IN VARCHAR2,column3 IN VARCHAR2,column4 IN VARCHAR2,column5 IN VARCHAR2)

||'dense_rank() over (order by ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_OBS'' ),4) DESC) AS rank '
||'FROM att_grp '
||'GROUP BY lev '
||'ORDER BY lev';
LOOP
FETCH cur_cross INTO stat_rec;
EXIT WHEN cur_cross%NOTFOUND;
IF stat_rec.rank = 1 THEN
DBMS_OUTPUT.put_line(column2);
DBMS_OUTPUT.put_line(stat_rec.lev|| ' = ' || TO_CHAR(stat_rec.chi_sq,'99.99') || TO_CHAR(stat_rec.chi_sig,'99.99'));
END IF;

Thank you Massimo. I tried your example but I recieve an error: PLS-00306: wrong number or types of arguments in call to "procedure1"
Here my Codes:
CREATE OR REPLACE TYPE stat_obj IS OBJECT(zeilen NUMBER,lev NUMBER, chi_sq NUMBER, chi_sig NUMBER);
CREATE OR REPLACE TYPE stat_tab IS TABLE OF stat_obj;
CREATE OR REPLACE PROCEDURE procedure1(table_in IN VARCHAR2,column1 IN VARCHAR2,column2 IN VARCHAR2, v OUT stat_tab)
IS
TYPE cur_crosstab IS REF CURSOR;
cur_cross cur_crosstab;
TYPE stat_tab_rec IS RECORD(lev NUMBER, chi_sq NUMBER, chi_sig NUMBER);
stat_rec stat_tab_rec;
BEGIN
OPEN cur_cross FOR 'WITH '
||'att_grp AS '
||'(SELECT '||column1||' as x1 , lev AS lev, '||column2||', '
||' CASE'
||' WHEN '||column2||' <= lev '
||' THEN 1 '
||' ELSE 2 '
||'END attribute_group '
||'FROM '||table_in||', '
||'(SELECT level AS lev '
||'FROM dual '
||'WHERE level >= (SELECT MIN('||column2||') FROM '||table_in||') CONNECT BY level <= (SELECT MAX('||column2||') FROM '||table_in||'))) '
||'SELECT lev, '
||'ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_OBS''),4) AS chi_square, '
||'ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_SIG''),4) AS significance, '
||'dense_rank() over (order by ROUND(STATS_CROSSTAB(x1,attribute_group,''CHISQ_OBS'' ),4) DESC) AS ranking '
||'FROM att_grp '
||'GROUP BY lev '
||'ORDER BY lev';
LOOP
FETCH cur_cross INTO v;
EXIT WHEN cur_cross%NOTFOUND;
--IF v_stat_tab.rank = 1 THEN
--DBMS_OUTPUT.put_line(v_stat_tab.lev || '=' || TO_CHAR(v_stat_tab.chi_sq,'99.99') || TO_CHAR (v_stat_tab.chi_sig,'99.99'));
--END IF;
END LOOP;
CLOSE cur_cross;
END;
CREATE OR REPLACE PROCEDURE procedure2
IS
v_zeilen NUMBER;
v_lev NUMBER;
v_chi_sq NUMBER;
v_chi_sig NUMBER;
v stat_tab;
BEGIN
procedure1(v);
SELECT zeilen,lev,chi_sq,chi_sig INTO v_zeilen,v_lev,v_chi_sq,v_chi_sig
from table(v);
DBMS_OUTPUT.put_line(v_zeilen||v_lev||v_chi_sq||v_chi_sig);
END;
Hope u can help me!!
