Can I modify system variables using advanced actions?
I am creating somewhat complicated quiz which involves an element not covered by the usual Captivate question types. Everything works fine, and I can keep track of how the quiz-taker fares in this element via a user variable. On the final results page, however, only system variables come into play.
What I want to do is the following. Let's imagine that the system variable for the final score (in points) is var_score. The user variable for the new element is var_new. I want the final score (which shows up on the final results page) to take var_new into account: the final var_score should be the unaltered var_score minus var_new. I could do this, e.g., via the Assign action. But I can't seem to make this work for the system variables for quiz scores. And I haven't been able to come up with any other solution. Does anyone have a suggestion? Thank you.
