I threw that form together just to show you the method, you must make it your own. Use the way it is done, add and remove items as desired.
Each combobox has an SQL statement (query) in its Row Source and here you collect any fields that you want from any table, add criteria, etc. Remember to keep the Column Count and Column Widths in sync. Once the user makes a selection you now have access to those fields and can display them. See how I have done it, on the AfterUpdate of the combobox I populate the fields on the screen, also they are available for use while the form is open. I don't know if you can do this in a macro, I don't use macros. You can play around with that. Another feature is to make fields invisible, such as the ChildID - you need the field later on but the user doesn't necessarily have to see it, it would just clutter up the form.
Another (maybe easier) way to display the data is to create a subform from the Assessor table and then when the user makes a selection in the combobox the subform will be linked to it via the ID and the data will be displayed. This will avoid manual population of each field (as I have done), which is fine for one or two fields but when you are displaying the whole table this is probably a better way.
