Thank you page not working

I can’t get the form to redirect to the thank you page after submission.

I have put this in my additional settings.

on_sent_ok: “location = ‘http://www.domain.com.au/thank-you’;”

I’m using version 3.4 of Contact Form 7.

I want to redirect to a thank you page so that I can track goal conversions in Google Analytics. Is there another method perhaps?
