inconsistent error

[TRM]

I am using automation to edit/accept changes to some word
documents from Access. The code follows. Occasionally
however, I receive an error "document not open"... It
does not always happen and occurs on the line
reading "With Active Document", next line "Dim lngCounter
as...". I THINK I have also gotten the error, "server
not avaiable" on this same line. Any suggestions??

Thanks for your time and effort!
