Google Analytics tracking not working

WordPress 3.8.1 running Biznizz theme
Contact form 7 Version 3.7.2
Google Analytics Universal code

I’m trying to get the Google Analytics goal tracking setup in Contact Form 7 and followed the instructions in this post by contact form 7.
https://contactform7.com/tracking-form-submissions-with-google-analytics/

The following symptom appeared.
1. “Message successfully sent” did not appearer after clicking submit.
2. Conversion was not tracked.
3. However, message was sent.

Any suggestion would be helpful ??

Here is the page I am working on.
