[Plugin: Contact Form 7] Troubling with contact form, analytics and confirmation message

i have a problem with the tracking code of google analytics. when i write
on_sent_ok: “pageTracker._trackPageview(‘/objetivos/reserva.html’);” on my aditional configuration box, the confirmation send ok of my form doesn′t work.
