A family of Microsoft relational database management systems designed for ease of use.
The subform should not be linked to the main form, i.e. the Link Master Fields and Link Child Fields properties should be blank.
Create the following event procedure for the subform:
Private Sub Form_Current()
If Me.NewRecord Then
DoCmd.GoToRecord acDataForm, Me.Parent.Name, acNewRec
Else
Me.Parent.Bookmark = Me.Bookmark
End If
End Sub
This will keep the main form synchronized with the subform
