Hi,

I have gone over and over my (very simple) script but can't see the cause of
the error "The target service name could not be found. Ensure that the
service name is specified correctly and/or the routing information has been
supplied." . The code is shown below. Please, please can someone enlighten
me in this new area.

Thanks.
