That’s not really what I am trying to do. I want my variation to increase the base price of my product by a certain amount. For my company I make bags and in this example let’s say the base price of a bag is $100. However, if you want to add foot studs to the bottom of your bag that will cost an additional $30. Also, instead of a button closure you want a zipper closure well that is going to be a $20 increase. Therefore, if you wanted to add both variations then the total price would be $150. However, you don’t have to get both so if a client only wanted to add studs then the price would be $100 + $30 so a total of $130. How would I make this add-on function work?
