       Your earlier response was great, but I didn't see it until I 
received this reply.


       I apologize for sending essentially the same question twice. It 
was not my intent.  I missed Duncan's reply and couldn't find my 
original email in my "sent" folder.  I concluded erroneously that I may 
have deleted the draft rather than sending it.


       Thanks again,
