Show next button on quiz revisit now working

So last issue here on my ELearning Curriculum. I watched Paul Wilson's video on showing next button on quiz revist and here's the AA with the user variable I created. 

Under the First AA Tab labelled Enter

Actions

Increment _question04 by 1

On the second AA Tab labelled check

If

-question04 is greater than 1

Then

Show next_btn 10

Now I have this AA with user variables for the first three questions and this AA works just fine but it's not working for the last quz question and I have no idea why.

Any Thoughts?
