How do I add Product Options?

Hi, I am new to OpenCart and cant find the answer for my question, asking for help.

Downloaded version 2 and installed on localhost.
Added product options (Years and Computers), and values.
Added product.

I find the place to add the options to the product, but what I need is relate one option with the other.

I am selling program licenses, and the options are Years, and Computers.
Whit different prices of course.

1 Year - 1 Computer = 25 USD
1 Year - 2 Computer = 35 USD
2 Years - 8 Computers - 98 USD
and so on

How can I do this ?

If one of the options is unique, just add in price in product-option tab. At least it would work for the example in your post above.

It is not a solution for some option combinations, though
