Facebook not showing full url -

i'm trying facebook work. kind of works gives wrong title. while messing around facebook button, noticed didn't finish url give me

www.mysite.com/product#

instead of

www.mysite.com/product#item1

if go

https://developers.facebook.com/tools/debug/og/object/

and come in right url shows in debugger, doesn't seem work on site.

here facebook code

<iframe src="https://www.facebook.com/plugins/like.php?href=http://mysite/product#item1"></iframe>

that´s anchor on page, facebook not read one. meaning, not separate url facebook. if want different metatags same link, have utilize parameters instead.
