[jQuery] Need Demo Help

[jQuery] Need Demo Help


I'm trying to learn jquery and the first sample I copied does not run
- I get an err in my FF3 console that says $ is not defined.
Here is my code:
<html>
<head>
<script type="text/javascript" src="../js/jquery/jquery.js"></
script>
<script type="text/javascript">
$(document).ready(function(){
    $(".btn-slide").click(function(){
     $("#panel").slideToggle("slow");
     $(this).toggleClass("active");
    });
});
</script>
</head>
<body>
</body>
</html>
