Change Price based on Select Option for Configurable products

Question

I have a product and three variations. So, when I change the options for the Size, I want to change the price dynamically for that option. For.eg. we have Standanrd, Large and X Large. And price is 15, 30 and 46 Resp. When Selecting Large, the price change to 30 and so on.

I read a lot in the Stackexchange or internet but could not find a right solution. The sample link to the page is http://bibliografi.co.uk/index.php/catalog/product/view/id/8262/s/COP090709009/

in View.phtml I have this

var optionsPrice = new Product.OptionsPrice(<?php echo $this->getJsonConfig() ?>);

and to display the price

          <tr valign="top">
            <td>Price:</td>
            <td><strong>
            <?php echo $this->getPriceHtml($_product, false) ?>
            <?php echo $this->getTierPriceHtml() ?></strong></td>
          </tr>

any help please
