Help with Drop Down Menus in Forms

I'm trying to create a form where the user enters their criteria with the help of a drop down menu and it brings back a summary of all info fitting that criteria. For example: using a drop down the user chooses the year "1999"; another drop down allows him to choose the month "01"; another would have a list of car types. Clicking a button would bring back a summary of data for that type of car for Jan., 1999. All the data is stored one table. How would I create such a form? I'm very good with SQL and decent with Access queries, so I'm not completely lost. I'm just new with forms and reports.
