What is difference between F9 and Shift+F9 in Access?

I created a form with a subform. I also have a text box on the form with a
dsum formula. The Dsum will calculate a total of the record that have a
check box in the subform checked. When you click on the check box to select
or deselect a record. the text box will recalculate if I press F9 but not if
I press shift+F9. I tried adding recal, requery, and repaint as events to
update the formula with no avail.

<F9> recalculates the fields in the window. <SHIFT><F9> requeries the
underlying tables. If the focus is on the subform, then <SHIFT><F9>
requeries the underlying tables for the subform only.

To get the text box on the main form to automatically recalculate the number
of records checked, try the following in the subform's check box's
OnAfterUpdate( ) event:

Private Sub chkDone_AfterUpdate()

On Error GoTo ErrHandler

Me.Parent.Controls!txtSum.Requery

Exit Sub

ErrHandler:

MsgBox "Error in chkDone_AfterUpdate( ) in" & vbCrLf & _
Me.Name & " form." & vbCrLf & vbCrLf & _
"Error #" & Err.Number & vbCrLf & Err.Description
Err.Clear

End Sub

.. . . where chkDone is the name of the check box on the subform, and txtSum
is the name of the text box on the main form.

HTH.
