Putting these lines:

cgi.popup_menu(opts) +
cgi.br +

inside the if statement doesn't work for me: I get a bunch of kEND 
errors.  If I move those lines outside the if statement, then no errors:

cgi = CGI.new('html4')
output = cgi.html {
  cgi.head { cgi.title { TITLE } } +
  cgi.body { cgi.h1 { TITLE }  +
    cgi.form('post') {
      if File.readable?(Filename)
        f = File.open(Filename,"r")
        opts = ""

        f.each_line do |l|
          l.chomp #does nothing
          inputs = l.split(',')
          puts inputs[0].to_s + ": "
          opts << "\"" + inputs[1].to_s + "\""
          2.times { inputs.delete_at(0) }
          until inputs.empty?
            opts << "[\"" + inputs[1].to_s + "\",\"" + inputs[0].to_s + 
"\"]"
            2.times { inputs.delete_at(0) }
          end
        end #each_line

        f.close
      end #if

      cgi.popup_menu(opts) +
      cgi.br +
      cgi.submit
    } #form

  } #cgi.body
} #cgi.html

cgi.out { output.gsub('><', ">\n<") }


I have no idea why that is the case.
