TypeError: $ is not a function this.pageWidth = $(document).width();

On the site I'm working on jQuery is not available on $, it is available on jQuery. I did see that you have code to pull in jQuery but that isn't working for me. Drupal on all sites, for instance, keeps jQuery away from $ and on jQuery

TypeError: $ is not a function

this.pageWidth = $(document).width();
gridwax.js (line 32)

Start at gridwax.js line 32 and inspect how jQuery is loaded and referenced. Reproduce the error on a Drupal-style page where jQuery is available as jQuery but not as $, then verify that the page-width initialization completes without the TypeError.
