Here is the page: http://www.billsprice.com/product.php?productID=339267

so its the comment box, I am having trouble when you visit, then click to another link on the site, then use the back button. it is throwing all my settings off for this comment form.

thoughts on how to get js to not change when people click back?
<script type='text/javascript'>
var form = document.getElementById('login');
setDefaultText(form.elements.response, 'Write a comment...');

function setDefaultText(field, text) {
    text = text || field.defaultText;
    if (field.value === '') {
        field.value = text;
        field.defaultText = text;
        addClass(field, 'faded');
    }
    field.onfocus = function () {
        removeDefaultText(this);
    };
    field.onblur = function () {
        setDefaultText(this);
    };
}
function removeDefaultText(field) {
    if (field.value === field.defaultText) {
        field.value = '';
        removeClass(field, 'faded');
    }
}
function hasDefaultText(field) {
    return (field.value === field.defaultText);
}
function hasClass(ele,cls) {
    return ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}
function addClass(ele,cls) {
    if (!this.hasClass(ele,cls)) ele.className += ' '+cls;
			document.getElementById('gg').style.height = '20px';
					document.getElementById('ggr').style.display = 'none';
}
function removeClass(ele,cls) {
    if (hasClass(ele,cls)) {
        var reg = new RegExp('(\\s|^)'+cls+'(\\s|$)');
        ele.className=ele.className.replace(reg,' ');
		document.getElementById('ggr').style.display = 'block';
			document.getElementById('gg').style.height = '80px';
    }
}
</script>
