For us to help you we really need you to post a zipped copy of the database on here using the "advanced" post option and "manage attachments".
If you want a combo box to "Add" names (or ID) to records then just create a query with the id, name and group and sort them by Name and then by Group.
Use the query to supply the data for your combo and you will have each person listed with their groups.
If you want two combos one for names and a second with groups based on the chosen name, you will need a second query fro the second combo and set it's criteria for the name column = to the 1st combo selection.
The first combo selection would have to use VB to "requery" the second combo to "pick up" te selected name.
The second combo would be "bound" to the "ID" field on the form.
