Analytics tracking not working properly

For some reason or another:

on_sent_ok: “_gaq.push([‘_trackEvent’, ‘Contact Form’, ‘Submit’]);”

isn’t working properly and its coming back with an uncaught reference error of _gaq is not defined.

This is resulting in the confirmation messages not working on form when the button is pressed.

Any help in working this out would be great.
