Dear Sean

Thanks for your email.  It is hard to diagnose your problem at a 
distance, but here is some general stuff:

-- the trivial.html file needs to be in a place that is served by your 
http server (is that the URL that is not found?  ie can you see the 
form in your browser?  it wasn't clear to me from your email.)

-- your web server needs to be configured to allow CGI scripts, and 
probably to specify one or more directories where such scripts are 
allowed to live.  This is often a directory called cgi-bin; but note 
that it is not enough just to create a directory with that name, you 
must tell your webserver through its configuration file(s) that it 
exists and that CGI scripts placed there can be run.  How this is done 
depends on which HTTP server you are running, and I cannot help you 
with that I'm afraid.

-- the trivial.R, R.cgi and .Rprofile files all need to be in one of 
the places where CGI scripts are allowed (by your HTTP server) to live.

I hope that helps.  Good luck.

best wishes,
David
