help to convert vba to vbs

Hi experts.

Can you help me to convert this macro to vbs script.

This macro is to select the last sap session.

Option Explicit


Sub test()


  Dim SapGuiApp As Object


  Dim oConnection As Object


  Dim Session As Object


  Dim SAPCon As Object, SAPSesi As Object


  Dim SAPGUIAuto As Object, SAPApp As Object


  Dim NumOfRows As Long


  Dim Counter As Long


  Dim SAP As Object, SAPGUI As Object, SAPConnections As Object


  Dim cntConnection As Long, i As Long, SAPConnection As Object


  Dim Sessions As Object, cntSession As Long, j As Long


  Dim SessionExists As Boolean


 


  Application.ScreenUpdating = False


  NumOfRows = ActiveSheet.UsedRange.Rows.Count - 3


  SessionExists = False


  On Error Resume Next


  


  Set SAP = GetObject("SAPGUI")


  If Not IsObject(SAP) Then


    Exit Sub


  End If


 


  Set SAPGUI = SAP.GetScriptingEngine


  If Not IsObject(SAPGUI) Then


    Exit Sub


  End If


  Set SAPConnections = SAPGUI.Connections()


  If Not IsObject(SAPConnections) Then


    Exit Sub


  End If


  cntConnection = SAPConnections.Count()


  For i = 0 To cntConnection - 1


    Set SAPConnection = SAPGUI.Connections(CLng(i))


    If IsObject(SAPConnection) Then


      Set Sessions = SAPConnection.Sessions()


      If IsObject(Sessions) Then


        cntSession = Sessions.Count()


        For j = 0 To cntSession - 1


          Set Session = SAPConnection.Sessions(CLng(j))


          If IsObject(Session) Then


            SessionExists = True


          End If


        Next j


      End If


    End If


  Next i


    


  If SAPConnection Is Nothing Then


    MsgBox "Error.. no SAP session could be found"


    Exit Sub


  End If


      


  With Session
  .findById("wnd[0]").maximize
 .findById("wnd[0]/tbar[0]/okcd").Text = "/nfbl3n"

  End With


End Sub
