Parallax not responding in an iFrame

I put an Edge animate file into an iframe on SquareSpace, but the parallax scrolling function stopped working. I used the following code on my stage and it works great when I put it into a normal browser, but just not in the iframe. Any ideas if I should put the javascript somewhere else or if there is a better way to insert it?

yepnope({

  load:"http://cdn.edgecommons.org/an/1.0.0/js/min/EdgeCommons.js",

  complete: function(){

  EC.debug("Commons ready: "+EC.VERSION);

  EC.Parallax.setup(sym);

  }

});
