I developed a Donation Retrieval Information System, DoRIS for short, which gathers data for and gives donors date-specific reports to aid in filing taxes. (Updated monthly; reports run annually).

The search form uses parameters to retrieve records in a donor report (donor, start date, and end date). I've added a list box for a third parameter in the search form (the year of the date field) but need help to figure out how to implement.

Selecting only the year would save a couple of steps in running the annual report, although I need to keep the date parameter for other querying needs (for example, by month). How do I add this final parameter?

Thx in advance for any help you can provide.
