javascript code for price

[gene]

I am creating a javascript code where a page will show the amount of "savings in $" and the "% savings". I used var [-- PRODUCT.Price --] and var [-- PRODUCT.SaleAmount --]. However, when the script execute it will get the amount in the database with a dollar sign? How do I get rid of this dollar sign in the code? Or do I miss something? Need your help. Thanks.

Prices are always displayed with the currency symbol. You will probably need to do something in your code to strip it off if you need to use it for calculations.

Anyone here who could me out or give suggestions?

I pull the discount for pricing from the Coupon name that ShopSite stores in the customer cookie. Then calculate the discounted price for display.
ie: "|DIS30Toyota Corporation"

function disPrice(listPrice)
{
var cookie = document.cookie;
var discount = cookie.indexOf("|DIS");
var signedIn = cookie.indexOf("|yes");
var Price = listPrice;
if ((discount != 0) && (signedIn != -1))
{
var disPercentage = cookie.substring(discount + 4,discount + 6);
var workPrice = listPrice.substring( 1, listPrice.length);
var locComa = workPrice.indexOf(",",0);
if (locComa)
{
workPrice = workPrice.substring(0,locComa) + workPrice.substring(locComa+1,workPrice.length);
}
var Price = (workPrice * ((100 - disPercentage)/100)).toFixed(2);
if (Price.length>6)
{
Price = Price.substring(0,1) + "," + Price.substring(1,Price.length);
}
Price = "$" + Price;
}
document.write(Price);
}

<div class="recDPRICE"><script language="javascript">disPrice('[-- PRODUCT.Price --]');</script></div>
