Re: cgi prob.

You need a line like the following:

  echo "Content-type: text/html"
  echo 

when producing your http header for the browser..  This header
finishes at the first blank line (and isn't part of the displayed
page).  Try running your script at a shell prompt to check that you
don't have any other undesired blank lines, and that you get the
desired output.
