Checkbox front end addition throws javascript error?

[porlhews]

Hi All,

I've failed to transfer my form from joomla 2.5 to 3.3, so I've bitten the bullet as recreated it manually within my my site (i.e. a fresh installation of fabrik 3.2).

I've got a multi-checkbox element which has front end additions enabled. When I try to add an option in the front end, the following javascript error is raised:

Uncaught TypeError: undefined is not a function

Any ideas?

The usual credentials:

Joomla 3.3.6
PHP 5.5.16
Chrome

Thanks in advance,

Paul Hughes

Meant to say - I'm using the standard protostar template.
