[jQuery] tutorial code doesn't work :-(

[priti]

hi,

I am relatively new in jquery.I just installed and was sailing thru
tutorial.But somehow i was not able to run following code
$("a")
   .filter(".clickme")
     .click(function(){
       alert("You are now leaving the site.");
     })
   .end()
   .filter(".hideme")
     .click(function(){
         alert('hide');
       $(this).hide();
       return false;
     })
   .end();


------------
html
 <a href="http://google.com/"; class="clickme">I give a message when
you leave</a><br/>
 <a href="http://yahoo.com/"; class="hideme">Click me to hide!</a><br/>
 <a href="http://microsoft.com/";>I'm a normal link</a><br/>

i installed the latest version.

Can someone explain where i might be missing.

Regards,
Priti
