Recordings not playing on iPad 2

I am using Storyline to create software simulations and walk throughs.  The recorded the simulation in Storyline and they do not work when I view the couse on my iPad 2 using the latest version of safari.

I have the slides set to advance by the user.  The next button does not work.

I also have the slide trigger set to advance to next slide when the timeline ends and that does not work.

Any help woud be appreciated.
