Show Attempts Left

Hi, 

I've got a 10 question quiz, and the user has 5 attempts total to pass with an 80% score. 

• I have Attempts set to 0 because I have feedback set to none
• I have a variable called Attemptsleft which has a default value of 4
• On my Results screen, I have a Retry Quiz button, and a Review Quiz button. 
• I want Attemptsleft to reduce by 1 every time the user clicks Retry Quiz
• I have a layer trigger on the Failure layer that says:
  • When the timeline starts on this layer
    • set state of Button 2 - "Retry Quiz" to disabled
      • if attemptsleft = value 0
• I have a box on my Failure layer on the Results slide that has a variable reference that shows Attempts Left to the user
• The triggers on the Retry button are as follows:
  • When user clicks Button 2
    • Reset results 1.18 Quiz Results
      • if attemptsleft > value 0
    • Jump to slide 1.8 question 1
      • if attemptsleft > value 0
    • Subtract value 1 to attemptsleft

The only thing is, Attempts Left doesn't show a count down, it just shows the number 4 no matter how many attempts the user goes through. 

Can someone help? 

Thanks!
