I would like my users to choose a value from a list box that gets entered
into the field of a query.  For example, a record is pulled by a 4 digit ID,
yet to see the progress of sales for this ID, many months need to be scrolled
through are compared to the current month (which is held static on the form).
I would rather them select from a box the month they want to compare and
have the fields be populated in the forms bound controls.  What is the best
way to do this?  I tried having the criteria of the query look to the control
on the form, but it doesn't allow the form to open without requesting the
parameter value first...I want the user to be able to see the form and choose
from the list box instead.  

Thanks for the assistnace in advance
