    Default Why doesn't my javascript calculator work?

    It can be found right here: Javascript Calculator

    I have javascript enabled on my browsers but it still doesn't work. I see the calculator but pushing the buttons does nothing :( Any help is appreciated

    My code is:
    XML Code: 
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Javascript Calculator</title>
    <style>
        <!-- CSS STYLES GO HERE -->
            .container {
			width:500px;
			height:500px;
		}
		.equ {
			width:99%;
			height:20px;
			font-size:20px;	
			text-align:right;
			margin-bottom:15px;
		}
		table {
			border:1px solid black;
			padding:5px;
			width:100%;
		}
		table td {
			margin:3px;
			text-align:center;
			width:20%;	
		}
		.buttons {
			width:100%;
			height:50px;
			font-size:15px;	
		}
	</style>
    <script type="text/javascript" src="javascript.js">
	</script>
</head>
<body>
	<div class="container">
    	<table cellspacing="0">
