vb.net combo box tied to access db

I have an app built in vb.net which includes a combobox that ties into an access database field (2 options - Staged and Catalogued).  Everything displays fine and the correct result appears, but in my combo dropdown, i get Staged and Catalogued multiple times, since theyre used multiple times in the access table.  In my combobox, i want its data source to be tied into the access field, but only show those items once.  Any ideas?

Use Distinct or Group By in your SQL for the source for the combobox.

When i try to do a SQL query i get the below error:

"The schema returned by the new query differs from the base query"

I do this by clicking on the combobox arrow and then add query

Basically i have a database table that has multiple records, and one of those fields is a status field which is either Staged or Catalogued.  I then display that access database in vb.net using the database wizard.  I also allow edit access from the same vb.net form that displays it.  For the status field, i use a combobox, which is databound to the access db status field.  When i click the drop, rather then it display duplicates because if i have 3 records that are all staged, its going to list staged three times in my combobox, how do i avoid have all show, i just want it to show two options Staged and Catalogued.

But then the source for the combobox should not be the current dataset but another - using static values or another datatable - that returns only two options selectable.
