您必须保留记录集：

Private Sub txtsearch_Click()

    Dim rs As DAO.Recordset

    If IsNull(Me!Searchbar.Value) = False Then
         Set rs = Me.RecordsetClone
         rs.FindFirst "[PONumber]=" & Me!Searchbar.Value
         If rs.NoMatch Then
             MsgBox "No record found", vbOKOnly + vbInformation, "Sorry"
         Else
             Me.Bookmark = rs.Bookmark
         End If
         Me!Searchbar.Value = Null
     End If

     Set rs = Nothing

End Sub
