Well, Let's say I took a class March 1, 2005.  You are saying that the
training will expire March 1, 2006, right?  If you always require the
training one year later, then you don't need to store a new field for that.
You *know* that it expires one year later, right?

To run a report today, you would simply build a query to pull all records
where the training was done between February 24, 2005 and March 24, 2005.
Correct?  Those people are the ones who must retake that class in the next
30 days.

If all that logic is correct, then you really only need two fields in your
table (Name, DateTrained).

To create your report, you must create a new query.  Include the two fields
from your table.  In the "CRITERIA:" under the DateTrained, you have to put
some kind of criteria to tell it to only pull records where the date is
between February 24, 2005 and March 24, 2005.  The most obvious way to do
this would be to put...

Between 02/24/2005 and 03/24/2005

That query could then be used as the record source for your report.

Now, doing it like that means that you would have to go in and revise the
criteria in your query every time you run it.  Let's improve on that and use
some variables instead of entering set dates.  To do so, change that
"CRITERIA:" entry to the following....

Between DateAdd("m",-12,Date()) And DateAdd("m",-11,Date())

That will give you all the records where the DateTrained is between the
current date minus 12 months and the current date minus 11 months.

Hope that helps.
