I have this interaction where I ask the user to compare their answer to mine and score themselves by clicking one of the tick boxes. I then have a score at the bottom for visual effects to tell them how many they have correct. Now I couldn't use the survey quize as it doesn't count/score. So I inserted check boxes. I wrote variables for each check box I needed to count and then a variable to count at the bottom. I have two problems with this:
1. You can tick more than one per line - How do I make it so you can only choose one, but you can change your mind.
2. Because the trigger says change the value to 1 when the user clicks the check box on condition the check box's state is selected. Yes = 1, No = 0. So when the user clicks yes it counts 1, then they change their minds and un check it and tick no. The counter at the bottom will still show 1 for yes and not take it back to 0 as yes is un checked. - How can I fix it to only count when the yes check boxes are selected and not to count them when they are un checked?
