PLEASE HELP, i'm running out of time, .......sample data included..!!

Question

Hi, i need some help.
my query is:
SELECT CANTEACH.LECTURERID, LECTURER.SURNAME, LECTURER.FORENAME, MODPART.MODPARTID, MODPART.MODPARTDESC, MODUL.MODULNAME, MODUL.MODULEVEL
FROM CANTEACH, LECTURER, MODPART, MODUL
WHERE CANTEACH.LECTURERID = LECTURER.LECTURERID
AND MODPART.MODULID = CANTEACH.MODULID
AND MODPART.MODPARTID = CANTEACH.MODPARTID
AND MODPART.MODULID = MODUL.MODULID
<----------------------------------------------->
AND CANTEACH.LECTURERID = 'L'
OR CANTEACH.LECTURERID = 'P'
AND NOT CANTEACH.LECTURERID= ('L','P')
<-------------------------------------------------------------->
this was my first guess, i know it's wrong, thought i might be able to work it out from the errors, but no luck, I need help on this one.
i'm trying to ask the db, which lecturer can teach 'only' L OR P but not both togther.
thanks in advance
Jd.
