Yesterday this page looked fine and today it's not (http://iphonebuy-host1.gaiahost.net/index.html) Clearly I must've inadvertently deleted or changed something but I can't figure out what!

There is a form embedded in #reviews-code using JavaScript, but it is suddenly not displaying. Also #reviews is not expanding to fit its contents any longer. I should say that I know nothing about JS and just copied the embed code from re-vu.com. Having repeatedly and thoroughly checked my CSS and HTML, I'm inclined to believe there is something up with the JS. CSS is below:

Code:
#reviews {
background:#F2F2F2;
width:57em;
height:100%;
margin:-1.5em 0 2em 0;
padding:1em 1.5em 1em 1.5em;
border-radius:1.5em;
-moz-box-shadow: 0 2px 2px 2px #ccc;
-webkit-box-shadow: 0 2px 2px 2px #ccc;
box-shadow: 0 2px 2px 2px #ccc;
}

/** Reviews text box **/
#reviews-text {
background:#fff;
width:14.8em;
padding:.5em .8em;
border-radius:1em;
float:left;
-moz-box-shadow: 0 2px 2px 1px #ccc;
-webkit-box-shadow: 0 2px 2px 1px #ccc;
box-shadow: 0 2px 2px 1px #ccc;
}

/** container for embedded ReVu window **/
#reviews-code {
margin:0 0 .5em 17.8em;
padding:.5em;
width:38em;
background:#fff;
border-radius:1em;
-moz-box-shadow: 0 2px 2px 1px #ccc;
-webkit-box-shadow: 0 2px 2px 1px #ccc;
box-shadow: 0 2px 2px 1px #ccc;
}

And HTML/JavaScript:

HTML Code:
<div id="reviews">
<h2>Reviews</h2>
<div id="reviews-text">
