Fax Through Outlook 2003

In the past this code worked fine - now I get an error message:

The recipient's fax #'s appear in a temporary table named "testfax" ... the [FaxNumber] field already contains the "1" in the first position...
The Code:

Function FaxTEST()

    Dim MyDB As DAO.Database
    Dim rst As DAO.Recordset

    Set MyDB = CurrentDb()
    Set rst = MyDB.OpenRecordset("testfax", dbOpenDynaset)

        With rst
            Do Until .EOF
                DoCmd.SendObject acReport, "rptJobSiteMeeting", acFormatRTF, _
                    "[fax:" & ![FaxNumber] & "]", , , , , False
                .MoveNext
            Loop
        End With

    rst.Close
   
End Function

If I manually type: [fax: 1##########] and send the message from Outlook directly, it goes out fine... (I replaced the actual numbers with the "#" - for privacy reasons...)
