Global Options Dependency


I want to add two “Global options” with a price dependency:

Option A: (a1,a2)

Option B: (b1,b2)

the basic price is 10$, if a1 is selected price become 12$, if a2 is selected so price must be 12$*10%

The current cs-cart configuration allow only to have 10$*10% (it uses the basic price and not the calculated one)

Do you have any suggestion that can help me?


I'm running into a similar problem. The product option % increase only takes into account the base price and not the calculated price. Is there an way to change this?
