Attribute Price Change In Browse And Product Details

My website store using joomla virtuemart 1.1.6 shopping cart and currently showing attributes in the browse product page,

What i need is when someone selected different attribute, the price on that page automatically updated.

Work that need to be done:
1. Price Change when selecting different attributes on Browse Page (The attributes already on the browse page)
2. When the page load, make sure it load the price of the first attribute selected (ex: I have base price $0 and attribute(1) +$1, attribute(2) +$2. i want when the page load it showing as $1 not the $0)

Thats all,

Cheers,
