Checkboxes (Add/Remove Value when users tick and un-tick)
I'm having a challenge with creating an interactive checkbox where users have to tick the correct boxes to go on the next slide. Now what I've tried to do is create a variable with a value of 1 and created a trigger which adds 1 when the user checks a box. However, the issue is when the user would check a box and then un-check it, it would still add the value of 1 to the variable anyways.
So at the end of the quiz when the user would click submit it would indicate that the quiz is wrong. Because the user was unsure about his/her selections.
If someone could shed some light on this would be much appreciated.
