[ic] Product type

[Miguel Omar Carvajal]

Hi!

I am trying to setup a product which has an option(size) which changes 
the options and prices, I need IC to change prices when the user selects 
a different size. Kind of what macys does in the following site:

http://www.macys.com/catalog/product/index.ognc?ID=84842&CategoryID=436


when you select the size: Twin, Full or Queen the options on the bottom 
change along with their prices. How can I do this with IC?


Thanks in advance,
Miguel
