In order to connect a NationBuilder event with a Facebook event, you must first create your event in the NationBuilder control panel. After creating your event page, or selecting an existing event page in the overview display, go to Event Details > Social Media. 

In the Social Media tab under Facebook there are two options. When you click on the Publish to Facebook button you will be taken to a new event page in Facebook identical to your NationBuilder event page. Keep in mind that whichever Facebook account you are logged in as at the time will be the creator of the event. So if you have a Facebook page for your organization, you want to be sure that you are logged into that account before you take this step.

The other option for connecting these events is to create your event page on Facebook independently of NationBuilder. Make sure the information about the two event pages matches up! Then go into the corresponding event page in NationBuilder and go to Event Details > Social Media. Right above the button that reads Connect to an existing Facebook event, enter the url of that event, and then click the button.

Once your NationBuilder event page is linked to a Facebook event page, anyone who RSVPs for the event on Facebook will show up in your control panel dashboard and event dashboard as an RSVP for the NationBuilder event (because the two events are one in the same!). This way you will always have an accurate RSVP count.
