Not a valid bookmark.

Error 3159

You tried to set a bookmark2NFD9R0 to an invalid string.

This error can occur in Visual Basic if you set the Bookmark property to a string that wasn't saved from previously reading a Bookmark property.  The following code produces this error:

   Sub MyFunction

       Dim MyDB As Database, MySet As Dynaset

       Dim Placeholder As String

       Set MyDB = CurrentDB( )

       Set MySet = MyDB.CreateDynaset("Employees")

       Placeholder = "1"

       MySet.Bookmark = Placeholder ' Not a valid bookmark.

   End Sub
