BuddyPress.org

Could someone help me with adding extra sidebar (left) to my home page of BP default child theme please? I tryed the Buddypress Sidebar plugin, but it is not working with 1.5 I believe. I want the sidebar width 240. I added this code to my functions.php

// Area 6, located in the homepage. Empty by default.
register_sidebars( 1,
array(
'name' => 'Sidebar1',
'before_widget' => '<div id="%1$s">',
'after_widget' => '</div>',
'before_title' => '<h3>',
'after_title' => '</h3>'
)
);	

And this one to my home.php

But I can’t understand how to make a wright css for it to be on the left )
