how to change displaying order of products in wp ecommerce

I am working on a wp-ecommerce enabled site and am trying to change the display order of the products on the product grid page. Any help would be greatly appreciated.

In the WordPress backend select Settings | Store .

Select the Presentation tab.

Scroll down to the Product Page Settings section and change the value of the Sort Product By dropdown to: Drag & Drop

Now you are able to click on a product in Products | Products , hold it and drag it to the position in which you want it to appear.
