How to

I need help in figuring out if Opencart can do this by default or what kind of extension I need. Ok so...

I need to have the configuration of products to show.

eg. "Product Name Product Name Price from $10 - $20" when you click on on "Product Name Price from $10 - $20" it shows different radio or select size options of "10lb" at the price of $10 and option of "20lb" at the price of $20. So Product 10lb has its own model number, Product Code or sku and product product C has its own model number, Product Code or sku. When you select either one it updates with the respective prices and model number etc.

Can this be done with opencart or do I need an extension? If so not sure what to even look for. Any suggestions?

It requires an extension to do this, yes: http://www.opencart.com/index.php?route ... on_id=3028

@straightlight it states that link can't be found. What is the name of the extension?

Thanks

Sorry, link fixed. It should be working, now.
