Create Fuction Error PLS-00201: identifier 'T_VARCHAR2_TAB' must be declared

I'm trying to create function received from vendor and it will not compile.  I've googled but can't seem to find out why?

CREATE OR REPLACE FUNCTION CLARITY.tab_to_string_2
(p_varchar2_tab  IN  t_varchar2_tab, p_delimiter     IN  VARCHAR2 DEFAULT ',')
RETURN VARCHAR2 IS l_string VARCHAR2(32767);
l_str varchar2(32767) := ' ';
BEGIN

  if p_varchar2_tab.First is NULL and p_varchar2_tab.Last is NULL then
    return l_string;
  end if;
  FOR i IN p_varchar2_tab.FIRST .. 5 LOOP
    IF i != p_varchar2_tab.FIRST THEN
      l_string := l_string || p_delimiter;
    END IF;
    if i > p_varchar2_tab.LAST then
        l_str := i || ' ';
    else
        l_str := i || p_varchar2_tab(i);
    end if;
    l_string := l_string || l_str;
  END LOOP;
  RETURN l_string;
END tab_to_string_2;
/

I'm going to guess you probably need something like this..


create or replace type clarity.t_varchar2_tab as table of varchar2(4000);
