Layer not staying on screen and automatically advancing to next slide

Thank you for looking at this.  Although I have a work around (see below) I will take a look at what you've done and see if that works better than mine!  

I have found a work-around, although have not solved the actual problem.  Instead of using an Essay Graded Question, I inserted a Data Entry (text) field instead. I simulated the 'User must answer' condition that is on Graded Questions, by adding another layer that shows a prompt to "Enter your answer and click submit" if the variable TextEntry = blank.  The slide now acts as I want - if the user does not answer, they get a prompt to enter their response and click Submit. When they do that, the Feedback layer is displayed, showing the correct answer and stays on the screen until the learner click Continue to proceed to the next slide.  Fortunately, it is not critical for me to use a graded question here.
