Uncaught TypeError: undefined is not a function

Hi there,

We have a password strength indicator on our signup page however it stops working when the Better WordPress Minify plugin is installed.

Login page is here:
http://dogoodjobs.co.nz/login/

The strength indicator is also on this page working fine:
http://dogoodjobs.co.nz/submit/

I believe it is something to do with the following error:
Uncaught TypeError: undefined is not a function

As this error does not occur on the submit page, a google search suggests that it may be because the files are being concatenated with commas rather than semi-colons.
