I think this example should be fixed like this:

<% require 'cgi' # Require the CGI library
cgi = CGI.new()  # New CGI object
username = cgi.params['username'][0]
%><html><head><title>eRuby Test</title></head>
  <body>
    <h1>Testing eRuby</h1>
    <% if username.nil? # Print out the form asking for the username %>
      <form method="post">
        Please enter your username: <input type="text" name="username"><br>
        <input type="submit" value="Go">
      </form>
    <% else %>
      Welcome <%= username %>!
    <% end %>
  </body>
</html>
