Quiz question point values for incorrect responses

Hi All,

Following along here. I like the idea of not needing to set up a freeform, but instead use existing quizzes. I didn't use quiz banks, but otherwise tried to follow along with what Ben did (or my interpretation of same ), and created a 5-question T/F quiz with negative/positive displaying on correct/incorrect layers. I removed the percent from the results slide to just display scores.

Then I was wondering about creating a running score as the quiz progresses: each slide showing the tally to that point. I started out OK by creating a trigger with slide 1 showing 0, and then showing 10 or -10 depending on whether the answer was correct.

But then I began thinking I'd have to create a gazillion triggers as I went along because of all the potential scores

Slide 2 could = 20 if both answers to that point were right, -20 if both were wrong, 0 if  one was right and one was wrong

And that would grow exponentially for each added question (I think).

So is it doable?

I'm uploading what I did. I think I probably should have modified the correct/incorrect on the Feedback master instead of on each slide (I copied/pasted to save time, but still), yes?

Just through the quiz together...it's not anything I'm really using (obviously).
