[Help Wordpress] Slider not sliding and other issues

Hello,

Trying to get this working on my clients site: http://listandselltoday.com/

If you scroll down to the area with the Active MLS listings, SOld, and This is Cincinnati. The Active MLS listing is the right one, but it does not slide or anything. I am getting this error on the page: Uncaught TypeError: Object [object Object] has no method 'royalSlider'

Please help.

Thanks
