when I looked into the code,I found that there was not new code or changed code in the position of displaying product price in tpl_product_info_display.php. too wierd

The module does work, but your template is using different names for the <div> 's that are used to recognize where to change the price.

Also the code doesn't directly modify the template files but uses javascript to update the price. There are a few things that have to be correct about the existing site in order for the javascript to function. The plugin does work and the forum for the plugin contains most if not all of any issues encountered and how to overcome them.

Why not use the built-in functions? Set the product to priced by attributes and use the attributes controller to set up the prices.
