This Sql Command Make Me Sick

hello everyone...

after several days trying to find the right command.. i have to ask you
people...

this is the deal:

i have two tables related...
the first one is the master, the second the slave...
the first has fields like code, name, department and periodicity of
payment...
the second has the payment data... code, date of payment, amount to
pay...

not every one in the first table has the payment in the same month...
because a few people receives its pay one time in the month, and other
receives payment every two or three months (periodicity of payment)...

my trouble is when i want to see all the payments in one month of the
people from one specific department, because if somebody doesn't get
his payment (different periodicity) i have to see the code and name of
the worker AND the date and amount of payment in blank (in that
case)...

i thing that i must to be a simple LEFT JOIN but it doesn't work in
Access (i have a web asp page with and access database in this case)...

i don't know what to do.. please.. if somebody has some ideas.. i need
it...

thanks..

Enzo..

ps/.. my left join code:
SELECT table1.name, table2.date, table2.amount
FROM table1 LEFT JOIN table2 ON table1.code = table2.code
WHERE (((table1.departm)=53) AND ((table2.date)=#2/15/2006#));
