Drag and Drop Quiz - Setting variables to show answers after second attempt

I have created a drag and drop interaction. I set the trigger on the Try Again button to loop back to the drag and drop slide in order to reset the drag and drop options. What I want to happen is if the user gets the first attempt incorrect, I want the images to reset, when they select submit on the second attempt, I want the answer to show (which is on a slide layer). So basically they get two attempts, and on the second attempt I want the anwers to show. I cannot figure out where the variable should be adjusted, or where the conditions should be placed. I hope I explained what I am trying to accomplish.
