Hey Sarah,
sorry it took me so long to respond. I did take a look at your site. It looks like you may be using pricing by weight, but I'm not sure. If so, I have not looked into making the plugin work with that. The reason it's not working now is because your views based on your configuration are not writing in the html element that the jquery in the javascript function is searching for. The javascript functions could be reworked to find your proper element. If you need a working example you can visit
