Pooling questions- Not advancing

I am using Captivate 5....and have recently created a quiz using videos.  As part of the development, I have incorporated questions in the regular content (filmstrip), as well as created a question pool to randomize some of the questions.  When I view the project, the questions slides get "stuck" when it comes to the pooling questions.  It works fine with those that are in the regular content....any ideas on what I am missing????  I do  have videos incorporated on all of the slides, which has made the size of the file very large.
