Oracle Stored Proc returning null

I am a total noob when it comes to stored proces in oracle. I created this stored proc but it is returning null. It is just supposed to join all the records into one string. And I cannot use a function

Procedure SPECIFIEDMOTORVALUE

   (V_POLICY_KEY  IN VARCHAR2,
    V_SECTION_KEY  IN NUMBER,
    V_SUBSECTION_KEY  IN NUMBER,
    V_ITEM_SEQ  IN NUMBER,
    V_EQUIPMENTDESC  OUT VARCHAR2) IS

  V_TEMPDESC            VARCHAR2(2000);

    CURSOR CUR_SPECMOTOR IS
        SELECT MTS_DESCRIPTION
        FROM MOTORSPECIFIED
        WHERE MTS_POLICY_CDE= V_POLICY_KEY AND
        MTS_SECTION_CDE = V_SECTION_KEY AND
        MTS_SUBSECTION_CDE = V_SUBSECTION_KEY  AND
        MTS_ITEM_SEQ = V_ITEM_SEQ;

    BEGIN
        FOR REC_SPECMOTOR in CUR_SPECMOTOR LOOP
            V_TEMPDESC :=V_TEMPDESC + ', ' +
REC_SPECMOTOR.MTS_DESCRIPTION;
        END LOOP;

    V_EQUIPMENTDESC := V_TEMPDESC;      EXCEPTION
  WHEN OTHERS THEN
  V_EQUIPMENTDESC :='';
