Apparently you are using both jQuery and Mootools and both of them do use
$ as an alias to a core function. Probably the
$ function which is generating this error is the Mootools function. I’d suggest you to try to write your jQuery code using
jQuery instead of
$ so you can confirm my point is right or not.
