php - Facebook Login Button Not Clickable -

-

i tinkering facebook login button , while easy put button on page, when click it, nothing. has had experience?

i had code: 

<div id="fb-root"></div><script src="http://connect.facebook.net/en_us/all.js#appid=myrealid&amp;xfbml=1"> </script><fb:login-button show-faces="false" width="200" max-rows="1"></fb:login-button>

did need extra?

you can see button being rendered here: http://www.comehike.com

but when click it, nothing. :(

the javascript console shows me following message:

fb.login() called before calling fb.init().

so should call fb.init() after button has been loaded.
