Well, you're most likely using a free Extension, but that's only a DEMO, and does not work in real.
But since your did not link the Extension you use, it's impossible to judge ....
And the link you placed to your Site, does not work correctly either, so, next time, please
take care of such, or you just risk, to be ignored, by those, usually willing to assist.
