[Plugin: Google Analytics for WordPress] Implementation with Contact Form

I’m trying to make conversion funnel in contact form but it’s not working.

When you use Contact Form, there’s is a box creating the form call Additional Settings. It supposed to be this code correct but it’s not working for me:

on_sent_ok: “_gaq.push([‘_trackPageview’, ‘/gracias-presupuesto’]);”

And I’m trying this code as well:
on_sent_ok: “pageTracker._trackPageview(‘/gracias-presupuesto’);”

Does the plugin has something for the forms?
