Urgent Help...Quantity Price Break

[shoshoni]

Hi All,

 

I am wondering if it is possible to accomplish the following with any contribution.

 

I want the following options on the product info page

 

radio button 1 - 5 grams of product A $5.00

radio button 2 - 20 grams of Product A $10

radio button 3 - 40 grams of Product A $15

 

Quantity - Text Box

 

The user clicks on "radio button 3" and enters a quantity of 2 then " 2 X 20 grams of Product A" is added to the cart displaying $30.

 

Please suggest a contribution which can accomplish this (very urgent..please)

 

Thanks

 

Sam
