TypeError: result is not a function

TypeError: result is not a function

I'm trying to use  this plugin (I've also tried the derivative bsmSelect) and can't seem to get it working.
I have jQuery, the plugin .js, and my page .js all included, but on my page .js I get the error 

"TypeError: Result of expression '$kuj("select[multiple]").bsmSelect' [undefined] is not a function."

This is while doing var $kuj = noConflict(); earlier, and here is my page .js.

  1. $kuj(document).ready(function() {
  2.     $kuj("select[multiple]").bsmSelect({
  3.         sortable: true,
  4.         animate: true
  5.     });
  6. });
I have pretty much no idea what is going wrong, as I've tested via js console that the $kuj("select[multiple]") statement is indeed returning an object.
