Activate button top.

Hello
I started to do a site for Clean template.
But I do not know how to activate the button top.
How to do it?

Thank you.

Send link it may be it does no function due script conflict

Now I can not, that's still on the local host. Or is there any way to realties?
Thank you.

There are free PHP/MySQL hosts like hostinghood.com if you need this solved fast copy site there or wait until you finish dev so you can send me final URL. But note that this can mean you could have other problems because of same problem
