Adding variables from a pick many quiz
I'm trying to build an interactivity where users choose as many items as they want, and each of these items costs a certain value. These items are pictures.
I have set a variable "Choice", which has a different value depending on the picture. But what I'd really like to have is the total result, like a shopping basket, with the addition of all the choices the user does.
Is it possible to add the values and then show the user the total result?
I'd appreciate any comments on this.
Thank you very much in advance.
