I set price at 2 levels, and set 5 functions (such as accounting module) as attributes , each with 2 levels--yes and no(which means include the function or not)
If price of concept 2 is higher than concept 1, how can I make sure that No. of functions with "yes" level in concept 2 is larger than that in concept 1 (ie. if price higher, more attributes are presented with 'yes'. Alternatively, I also wonder how can I make sure the expensive option include all the functions in the cheaper option)
Thank you for your time.
