Sequence won't play

Hi--

I have a model, and am trying to get a simple sequence to play in Thingworx View (or the HTML Preview in Studio). I create the sequence in Creo Illustrate, and the PVZ file shows the proper animation in Creo View. When I put it into my experience, and connect a button to the "Play All" option for the 3d model object, I get Javascript errors when I click the button in preview mode:

Any ideas what to check or fix to make this work?
