Customizing the Review Quiz Functionality

Hi...and thanks in advance for taking a look at my issue. I am trying to create a quiz that allows learners to answer quiz questions in random order. Everything works fine until I answer the last question. Then, none of the triggers I set up work. I used a variable to determine if the learner should be taken to the quiz question menu or the results slide when they press Submit. This was working fine until I added a next button on the Review layer to allow learners to review each question. Now, my last question goes to the next question in line when the learner clicks submit. Is there a way to fix this or will I have to remove the next buttons on the Review layer. I am uploading a portion of the file to help explain what I've done. Thanks!
