I guess this is simple, but I'm stuck.
I am trying to write a simple app - Newspapers and their circulation by
town.
tables:
tblPaper - ID (autonum, key) and Newspaper (indexed)
tblTown - ID (autonum, key) and Town(indexed)
tblPaperTown - PaperID, TownID, DailyCirc, SundayCirc
I have a form, frmPapersAndTow ns, that opens with a combo box and the
nav bar at the bottom. Combo box is cbopaper.
Data: SELECT [tblNewspaper].[NewspaperID], [tblNewspaper].[Newspaper]
FROM tblNewspaper;
AfterUpdate:
Private Sub cboPaper_AfterU pdate()
Forms![frmPapersAndTow ns]![sfrmTownsForPap er].Visible = True
DoCmd.ShowAllRe cords
Me.cboPaper.Req uery
End Sub
Format: 2 cols, bound =1, width 0,2"
This works if I choose a paper from the dropdown box. But if I use the
nav bar on the bottom, nothing happens. The record count says 10
(correct) and the number changes, the screen blinks, but the data in
the combo box and on the subform stays the same.
I'm still new to forms - thanks.

What are you expecting to happen? Is the ComboBox bound or are you using it
to navigate on the main form? A ComboBox can be used for one of those
operations, but not both.

I am expecting the form to display the "NEXT" newspaper and all the
towns/circulation associated with it.
The combo box is unbound. I don't think I am using it to navigate on
the main form, but then again, I'm not sure I really know what
"Navigate on the main form means". I am using it to select the
newspaper for which the user would like to see the towns/circ. Nothing
else. Select a paper from the drop-down; see the subform with all the
towns/circ.
Sorry to be so dense - this is all new to me.

Sounds like you are inter-mixing different concepts.
Normally the MasterLink ChildLink properties of a subform will create a link
between one or more fields in the two data sets so that when you navigate in
the parent record you see the corresponding records in the subform. When
this is set correctly it won't matter HOW the parent form is navigated. You
could use the buttons, apply a filter, change the sort order, etc., and
regardless of the methof used the subform will stay synchronized.
Your MasterLink property appears to be pointing to the ComboBox and since
that is unbound it does not respond to record navigation of the parent form.
Ergo, since the subform is responding to the Unbound CombBox it is not
responding to navigation in the parent either.
Now, if you were to bind the ComboBox then any time you changed it you would
be editing the current parent record and I don't think you want that either.
What you want is to set the MasterLink property of the subform to the
appropriate field in the parent form so that the subform responds as you use
the navigation buttons. Then delete the existing ComboBox and add back a
new one making sure that the ToolBox wizard is enabled.
One of the wizard choices for a ComboBox creates a ComboBox that causes the
form to navigate to the record with the matching value selected from the
list. If you use that you will end up with a "Navigation ComboBox". It
will not be bound, but code will run each time you make an entry that causes
the parent record to move to a that record. With your subform MasterLink
now properly set it will stay synchronized with the parent form regardless
of whether you use the ComboBox to navigate or the normal navigation
buttons.
