msg1 = “Please enter info correctly”
msg2 = “”
else
msg1 = "Welcome username: "
msg2 = "You emails is: #{email} "
end

puts “Content-type: text/html”
puts "Server: Apache/1.3.3.7 (Unix) (Red-Hat/Linux) # Server
information "
puts

puts <<HTML

Ruby form test body {background-color:#111;color:#aff;font-family:Helvetica,Arial,Verdana,sans-serif;font-size:12px;} h1 {color:#aaa}
