ah well there’s your problem — you’ve got floating divs.. your best friend for those is create a style in your ‘style.css’ called.
.clear {clear:both;}
first check and see if it’s already in there.. if it is then don’t add another.
Otherwise…add the div I’ve added after your ‘right’ div something like this:
<div id=”right”>
(there’s some code in here)
</div>
<div class=”clear”></div>
and that’ll fix your issue 😀
