Calculating the Sum of Multiple Variable.
I have variables throughout my course, each of which has a numeric value. At the end of the course I have a slide showing the numeric value of each variable as defined by the learner (as they were prompted to do so during the course). I want the learner to click a "calculate" button so, by doing, it will add up the variables and display the total. In essence the operation is the addition of 1+2+3+4+5 to display the sum of 15. Whatever help can be offered would be sincerely appreciated.
