Product options setup
I have a product display with 2 products, so that a customer can chose which one to select, let s say one can cose between Product Big (20 cents) and Product Small (10 cents).
I then used Commerce Product Options and Commerce Product Attributes so the customer can do a second choice, let say between Product Normal and Product Extra, this second choice will introduce a variation in price, but the basic Products are just Big and Small.
Naturally at the end there are 4 possible variation of the 2 Products (Big Normal, Small Normal, Big Extra, Small Extra)
What I was not able to achieve is that when the customer makes the second choice (between Normal and Extra) the price will auto-update (as it happens with Big and Small), is there an inbuilt function or do I need to set Rules? Can anybody help with that?
