Changed the functions.php and now my blog is blank.

I’m new to codes and blogging. I simply wanted to get an extra sidebar. I went into functions.php and made a little change and now my blog is blank. Can’t even log in. Please tell me I will see everything in my blog again. ??

Here is the code I made changes to:
/**
* Register our sidebars and widgetized areas.
*
* uses register_sidebar
* returns the id
*/
if ( function_exists( ‘register_sidebar’ ) ) {
register_sidebar ( ( array(
‘name’ => __( ‘sidebar’, ‘simplecatch’ ),
‘id’ => ‘sidebar’,
‘description’ => __( ‘sidebar’, ‘simplecatch’ ),
‘before_widget’ => ‘<div class=”widget”>’,
‘after_widget’ => ‘</div>’,
‘before_title’ => ‘<h3>’,
‘after_title’ => ‘</h3><hr/>’
) );
}
?>

I’m using the simplecatch theme. ??
