sort recordset

[bbxrider]

its not exactly database, but is manipulating an ado recordset.
i create a rs, populate it and never save it to db, it is used for work only.
after populating it i want to sort it but the sort isn't working
the debugger doesn't complain about the sort stmt but it doesn't sort it???
would it be easier/more expedient to try and open it ordering it?

rs1.CursorLocation = adUseClient
   Set rs1 = New ADODB.Recordset
   With rs1.Fields
      .Append "url", adChar, 50
      .Append "periods1-5", adDouble
      .Append "periods2-6", adDouble
      .Append "periods3-7", adDouble
      .Append "reach", adInteger
   End With
   rs1.Open
++later in program+++
               With rs1
                  .AddNew
                  ![url] = rs.Fields(rs.Fields.Count - rs.Fields.Count).Value
                  ![periods1-5] = calc1Value
                  ![periods2-6] = calc2Value
                  ![periods3-7] = calc3Value
                  ![reach] = rs.Fields(rs.Fields.Count - 1).Value
                  .Update
               End With
++later in program+++
   rs1.Sort = "periods1-5"
   rs1.MoveFirst
   Do Until rs1.EOF
      Debug.Print (rs1.Fields(rs1.Fields.Count - rs1.Fields.Count).Value)
      etc

try
rs1.Sort = "[periods1-5]"
