Slide in plugin doesn't appear in website

Hi Hello,

I've installed the SLideIn plugin. And created a simple text just for test purposes.

The global settings I left default exept for the fact that Slidin should start after 1 second.

But no where on the homepage, the slide in appears.. Either logged in or out.

So did I do something wrong?

I Installed it here: http://design-b.webityourself.nl/

Please let me know.
Kind regards,
Steven
