Want to get my previous button to work

[dhrey]

I am creating a quiz app.
The issue I am having is with the previous button.
Here's the block I'm working on:

The issue is that the app didn't subtract the score if the current question option had been selected before clicking on the previous button. I have tried all I could. Help!!!

Should do it...assumes question numbers start at 1, score starts at 0
