Storyline customised quiz
I have designed a quiz in storyline that consist of freeform and non-freeform slides. I have added variables and triggers to calculate the number of answered questions and number of correct answers. However the variable doesn't calculate the numbers of given answers if the participant clicks "next" and skips answering altogether. Is there a way in which I could force the participants to give answer in a non-freeform quiz?
Thank you in advance for your help.
