Right, I have this contact page that loops itself and displays the appropriate error messages. My problem isnt with the actual functionality of the contact form but with the footer.

 

The footer is very simple and only includes

    <div id="footer">
    	<div class="container">
        
        	<div class="footer_column long">
                <center>All rights reserved. I am not responsible for the content of external sites. <a href="contact.php">Terms and Conditions</a></center>
		</div>
    	</div>
    </div>
</body>
</html>
<?php mysql_close($connection); ?>

 

When I include this footer it doesnt appear at the bottom of the page like it should, it does initially, but upon submission it appears half way up the screen.
