Javascript Validation Issues

[BurgerIV]

Hey guys,

I was asked to go through our product pages and fix validation issues I could find using the w3c validator for an e-commerce company I work at. I have validated almost everything but have been having issues with some javascript. I am more of a back-end developer so javascript is not my forte. Anyways here is the original code that was causing issues:
----------------------------------------------------------------------------
<script type="text/javascript">

var norm = {price};
var special = "{special_price}";
var list = {list_price};
var end = "{special_to_date}";
var endComp = parse_date(end).getTime();
var start = "{special_from_date}";
var startComp = parse_date(start).getTime();
var now = new Date().getTime();


var specialTrue = '<div class="special-price"><span class="price-label">Our Price: </span><span class="price" id="product-price">{special_price_formatted}</span></div>';

var specialFalse = '<div class="our-price"><span class="price-label">Our Price: </span><span class="price">{price_formatted}</span></div>';

var specialFalseAlt = '<div class="our-price alt"><span class="price-label">Our Price: </span><span class="price">{price_formatted}</span></div>';

if (isNaN(special) === false && endComp > now && startComp < now) {
document.write(specialTrue)
}else {

if (list <= norm){
document.write(specialFalseAlt)

}else {
document.write(specialFalse)
}
};
</script>

------------------------------------------------------------------------------

So the validator doesn't like all these divs in the javascript variables. So I changed it to this:

------------------------------------------------------------------------------

<script type="text/javascript">
var norm = {price};
var special = "{special_price}";
var list = {list_price};
var end = "{special_to_date}";
var endComp = parse_date(end).getTime();
var start = "{special_from_date}";
var startComp = parse_date(start).getTime();
var now = new Date().getTime();
var specialFormat = "{special_price_formatted}";
var priceFormat = "{price_formatted}";
var label = "Our Price";

if (isNaN(special) === false && endComp > now && startComp < now) {
document.getElementById('product-price').innerHTML += specialFormat;
document.getElementById('product-price-label').innerHTML += label;
}else {
if (list <= norm){
document.getElementById('our-price-alt').innerHTML += priceFormat;
document.getElementById('our-price-alt-label').innerHTML += label;
}else {
document.getElementById('our-price').innerHTML += priceFormat;
document.getElementById('our-price-label').innerHTML += label;
}
};
</script>

<div class="special-price"><span class="price-label" id='product-price-label'>&nbsp;</span><span class="price" id="product-price">&nbsp;</span></div>

<div class="our-price"><span class="price-label" id='our-price-label'>&nbsp;</span><span class="price" id='our-price'>&nbsp;</span></div>

<div class="our-price alt"><span class="price-label" id='our-price-alt-label'>&nbsp;</span><span class="price" id='our-price-alt'>&nbsp;</span></div>

----------------------------------------------------------------------------

I have tried many different variations of this with no luck. Any advice on this is appreciated.

For anyone who is curious the divs needed to be put before the javascript code.
