Not sure if that is what you want, but try that. You were missing a comma...


Code:
var blue_monkey = prompt("what is your favorite color?""Blue");
>

this should have been 
>
>
>
var blue_monkey = prompt("what is your favorite color?","Blue");
                                                       ^
                                                       Notice the comma
This is the code corrected

Code:
 <html>
     <head>
        <title>stuff</title>
  <script language ="Javascript">
  <!-- hide me
    var red_monkey = prompt("What is your name?","Ryan");
    var blue_monkey = prompt("what is your favorite color?","Blue");
    var green_monkey = "I hate you";
    var orange_monkey = "and I hate";
    var all_in_one = green_monkey + red_monkey + orange_monkey + blue_monkey;
  // stop hiding me -->
  </script>
     </head>
<body>
<script language = "javascript">
  <!-- 
     hide medocument.writeln(all_in_one)
  // stop hiding me -->
</script>
</body>
</html>
