Help fix my function to show status for all folders

Question

I have created a function (tow of them for the same purpose) but they are not working. They compile but when i call them I get null result.
What I want to do is get folder status for all folders in the database. There is a table called folder with status code, and another table called validstatus with the statuscode description
So when you look at the older you just see the status code which is a number but then using the function you will get the desription of what that code means.
Here IS THE function. Maybe I am not doing it right when I call them.
CREATE OR REPLACE FUNCTION f_folderstatus (v_folderrsn IN NUMBER)
RETURN VARCHAR2
IS
v_return VARCHAR2 (128);
BEGIN
SELECT distinct vs.statusdesc
into v_return
FROM folder f, validstatus vs
WHERE f.statuscode = vs.statuscode
AND f.folderrsn = v_folderrsn;
RETURN v_return;
END;
When I call them using this statement I get null
select f.folderrsn, f_folderstatus3(vs.statusdesc)
from FOLDER F, validstatus vs
where f.statuscode = vs.statuscode

Answer 1

Now how do I create a function to give folder status for all foldertypes? I will then use this function in a package.
The Folder table has the following columns:
NAME Null? Type
FOLDERRSN NOT NULL NUMBER(10,0)
FOLDERTYPE NOT NULL VARCHAR2(4)
STATUSCODE NUMBER(10,0)
SUBCODE NUMBER(10,0)
FOLDERDESCRIPTION VARCHAR2(4000)
FOLDERCONDITION VARCHAR2(4000)
FOLDERNAME VARCHAR2(80)
The validstatus table has these columns:
NAME Null? Type
STATUSCODE NUMBER(10,0)
STATUSDESC VARCHAR2(80)
