[racket] try Racket

hi,
as I mensioned befor I want to create a simpel online cours for
programming! TryRacket is  just what i looked for but I want it to be much
easyer and the explaination must be in an other language not in english!
how can I embed the javaScript  console of TryRacket in my page so that it
will be also able to evaluate and get results!
I already see the console in my page but i can't get any result wenn i
enter a symbol or any element!
and do i need any permitions to use the console? Creating the online course
is a research project of me!
thats how I add the JavaScript in the body of my html(just like
tryracket.org):

 <script src="/js/jquery-1.4.2.min.js" type="text/javascript"></script>
 <script src="/js/jquery.console.js" type="text/javascript"></script>
 <script src="/js/tryrkt.js" type="text/javascript"></script>
 <script type="text/javascript">
 evalUrl = "/;((%22k%22%20.%20%22(1853%201%2093643149)%22))";
 </script>

what should I consider, please!
