Seeing a script on the mailchimp form of my site, see footer section:

(function() { window.mc4wp = window.mc4wp || { listeners: [], forms: { on: function(evt, cb) { window.mc4wp.listeners.push( { event : evt, callback: cb } ); } } } })();

I tried to add the following CSS, but nothing changed: div#mc4wp_form_widget-2 script {
display: none !important;
}

The page I need help with: [log in to see the link]
