Date query allowing user to enter dates

HI

I have a DB where I am trying to set up a search criteria using 2 tables and
one field out of each.

Table - Services Field - Service
Table - Appointments Field - Appointment Date (format = dd/mm/yyyy)

How can I set up a query where the user can input to select appointments
between 2 dates ie: 01/04/2010 - 30/04/2010 and service (ie exams)

I notice when I do a filter it allows me to select the dates from the
calendar - can this be done in a search criteria and would I be able to make
the list of services available in a drop down box.

I am relatively new to DB and don't use it often so need easy instructions.

many thanks

Irene
