PIVOT/CROSS TAB IN TOAD 12.5.1.1

I was wondering if you could help me understand why the code for pivoting in Toad is not working. 

I performed this in Access successfully and then tried doing this in Toad with no success.  This is the code Access created.  I continue to receive the error 'SQL Command Not Properly Ended' when I try to run this.  I performed an internet search using the syntax for 11.5, and still got errors.

Thanks for any help you can provide.

USING ACCESS CODE:

SELECT HMOCOMMALL_MEMS.MEMBID,
 Sum(HMOCOMMALL_MEMS.MMS) AS TOTMMS

FROM HMOCOMMALL_MEMS

GROUP BY HMOCOMMALL_MEMS.MEMBID

PIVOT HMOCOMMALL_MEMS.YEARMON;

USING CODE FOR 11.5, I get "invalid SQL statement"

SELECT HMOCOMMALL_MEMS.MEMBID,
 Sum(.HMOCOMMALL_MEMS.MMS) AS TOTMMS

FROM .HMOCOMMALL_MEMS

PIVOT (SUM(HMOCOMMALL_MEMS.MMS)
           FOR HMOCOMMALL_MEMS.YEARMON
          IN  ('201501','201502','201503','201504','201505','201506','201507','201508','201509','201510','201511','201512'));
