Magento Price Not Updating

We've recently installed Simple Configurable Products on our 1.4.2.0 Magento install but the price on the product isn't updating when the user selects an option, if you configure the product and add to cart the price show's up correct in the cart, just not on the product at the ti开发者_运维技巧me of selection.

If anyone could help out on this that would be great.

If the price and availability are not showing on simple/virtual/downloadable product page when there are no configurable/custom options.

The Solution is as follows:

Go to: app/design/frontend/base/custom theme/layout/

• Open the catalog.xml file
• Replace (line 279):

<block type="catalog/product_view_type_simple" name="product.info.simple" as="product_type_data" template="catalog/product/view/type/simple.phtml">

With:

<block type="catalog/product_view_type_simple" name="product.info.simple" as="product_type_data" template="catalog/product/view/type/default.phtml">
