working with number variables
I am new to Storyline and having trouble with number variables. I have a slide with a number of objects that can be selected to make an emergency kit. I can drag and drop all the items, right or wrong. What I would like to do is the have the number of items selected (either right or wrong) stop at a certain number. Say there is 10 objects but as soon as you select 5 ( any 5), you cannot pick any more. How do I set the variable?
Also I would like to give points for each correct one selected and make the points additive. How do I set the variable?
