Why is my Footer not sticking?
===

I'm in the process of re-doing my site - It's being built as and when I have time - I'm having a bit of a problem with two of the four pages with regards to the footer - I'm not too sure why it's not working as it seems to be working alright on two of the pages. I'm using the technique from here: (ryanfait.com/resources/footer-stick-to-bottom-of-page/)

I'm using these values in my CSS:

        /* BOTTOM BAR */
    
    .wrapper {
    	min-height: 100%;
    	height: auto !important;
    	height: 100%;
    	margin: 0 auto -122px;
    }
    
    .push, .footer {
    	clear: both;
    	width: 100%;
    	height: 122px;
    }
    
    .footer {
    	text-align: right;
    	padding-right: 0px;
    	padding-left: 0px;
    	clear:both;
    	background-color: #2e2e2e;
    	-moz-box-shadow: 0px -1px 0px rgba(0,0,0,0.1), inset 0px 1px 0px rgba(255,255,255,0.6);
    	-webkit-box-shadow: 0px -1px 0px rgba(0,0,0,0.1), inset 0px 1px 0px rgba(255,255,255,0.6);
    	box-shadow: 0px -1px 0px rgba(0,0,0,0.1), inset 0px 1px 0px rgba(255,255,255,0.6);
      	border-top:1px solid #36383D;
    }
    
    .bottom_content {
    	width: 900px;
    	margin-left:auto;
    	margin-right:auto;
    	padding-top: 25px;
    	border: 0px;
    }
    
    .copywrite {
    	float: left;
    	text-align: left;
    	padding:0px;
    	margin-top: 0px;
    	clear: both;
    	font-family: Helvetica, Arial;
    	font-size:24px;
    	font-weight:300;
    	color: #3c3e43; 
    }

- It's working fine on here: http://bit.ly/MlV6JP 

But not on here: http://bit.ly/NfVoRR
Or the about page (/test/test_about.php)

I've tried a number of different things, but to no avail! Starting to tear my hair out a bit with it, so any advice would be massively appreciated
