Slider not sliding

http://sandyjablon.nationalseoexperts.com

Beautiful full width slider – but it won’t change images (I have four loaded).

I disabled all plugins, but that didn’t work.

I also enabled the cache thing in Settings, but that did not work either.

I also switched themes. Again, no luck.

Help!

Can you please let me know what I may have done wrong?
