Where did you get this use_named_parameters() subroutine from? I looked at the CGI docs and googled, but I couldn't find anything. So I'm inclined to say that that particular error has nothing to do with the fact that your script "doesn't do jack". Just delete it.

Also, "doesn't do jack" isn't exactly useful for debugging. You will probably have a better luck getting responses if you describe what you do (did you just load the page? did you pass some parameters to the CGI?), what kind of results you expected, and what you actually got
