Contact form tracking with GA

Tried add this code to functions.php in ‘child theme’, but it breaks the site. Am I doing this wrong? Thought latest GA didn’t require the funny codes at the end there from the Enfold example: https://kriesi.at/documentation/enfold/add-onclick-event-to-the-contact-form-submit-button/

If those “XXX/XXX” codes are required, how do I find / generate them in GA?

Thanks!

// ADD GA TRACKING TO EMAIL FORM

add_filter('avf_contact_form_submit_button_attr','avia_add_submit_attributes_to_cf', 10, 3);
function avia_add_submit_attributes_to_cf($att, $formID, $form_params){
  $att = "onclick=\"_gaq.push(['_trackEvent','Contact Form Send','Click/Touch','Footer']);"";
  return $att;
}
