a second sidebar

Hello,
(i’m french excuse my words)
I use this template for the Red Cross. And we need two sidebar.
So i duplicate ->index.php on indextwo.php and sidebar.php in sidebartwo.php,
in function.php i ducplicate the part (lign 20-32;60-145) of sidebar and i replace the name sidebar on sidebartwo.
I put the information (get sidebartwo…) in indextwo.php, i put sidebartwo in theme-compat, and i put in the theme Flato.

I don’t understand what i do wrong, and each time, i have the message erreur *********************************************
{
global $content_width;

if ( ! is_active_sidebartwo( ‘sidebartwo-1’ ) || is_page_template( ‘full-width-page.php’ ) )
$content_width = 995;
}
add_action( ‘template_redirect’, ‘themememe_content_width’ );

*************************************************************************
So do i need touch any another page.php ? and where ?
Thank to anser me.
Enjoy et my best regard.

PS i do this for a passion, not a work.
