Linking combo box to subforms

[Clydy]

Page 1 of main form/with tabs lists information such as
address, city, etc. (Primary key is LocID). I have linked
a subform to it that has a drop down box so I can choose
what type of building is located at this address (Primary
key BuildingID). I have linked another subform to the
Building subform with a dropdown box (RoomID)that I can
choose what type of rooms are in the building (a.e.
livingroom, den, etc.)(Primary key BuildingRoomID).
On Page 2 of the form I want to have a dropdown box that
will list the rooms I have selected in the previous
subform. I have tried several different ways. I keep
getting a combo box that lists all rooms to several
locations. Can someone help

Clydy,

In the table where the rooms are listed, you have a BuildingRoomID
primary key field, and also, I presume, a BuildingID field as a foreign
key field to the Buildings table, right? Ok, your the rowsource of your
combobox on the second page needs to be a query which refers to the
BuildingID on your first subform. Without knowing more details of your
actual tables, I can't be specific, but the SQL of the query for the
combobox rowsource will be something like...
SELECT RoomID FROM BuildingRooms WHERE BuildingID =
[Forms]![MainForm]![BuildingSubform]![BuildingID]

You will need to set the rowsource of the combo box to something along the
lines of:

SELECT ColumNames FROM SourceTable WHERE BuildID = Forms!FormName!CboName

I am guessing ColumnNames will be RoomID, RoomDesc
I am guessing SourceTable will be something like tblRooms & contain BuildID,
RoomTypeID
