[Plugin: Contact Form 7] Analytics and messages

I’m running into an issue that I’ve seen other people have had but can’t find a solution that works. When I add the line of code to make Google Analytics work: on_sent_ok: "pageTracker._trackPageview('/contact/submit');" I no longer get a success message (though I do get the correct email.) Instead the rotating arrow just keeps spinning.

I’ve tried with old and new Google tracking codes, I have tried this line I saw somewhere: on_sent_ok:"_gaq.push(['_trackPageview', '/contact_form_sent']);", I’ve looked for javascript errors and haven’t found any.

Any ideas?

Here is one of the forms I’m using (on the sidebar): http://xcentric.com/consulting

Thanks!
