Quiz and variables
I'm trying to make a quiz where the user (in slide 1) can choose between three different categories. When the user is done with a category he/she will come back to slide 1 and will be able to pick a new category and to see the total score point as he/she progresses. So let's say I've done two out of three categories (each worth 10 points when answered correctly). Then I want to come back to slide 1 and see that the score board shows "20" points.
The category part is fine, I just don't know how to use the result slides and variables in the right way to display the total score point. Is this possible? Please help. :)
