Excerpt Length

The Subscribe2 FAQ page explains how to adjust the excerpt length.

I tried creating a new Snippet function in an effort to set the excerpt length.

function excerpt_length() {
    //return number of words you want the excerpt length to be.
    return 30;
}

add_filter(‘s2_excerpt_length’, ‘excerpt_length’);

However when I try activating the function I get the following error message:

Fatal error: Uncaught Error: Undefined constant "‘s2_excerpt_length’" in /home/ptcondo.org/wp-content/plugins/code-snippets/php/snippet-ops.php(575) : eval()'d code:6 Stack trace: #0 /home/ptcondo.org/wp-content/plugins/code-snippets/php/snippet-ops.php(575): eval() #1 /home/ptcondo.org/wp-content/plugins/code-snippets/php/snippet-ops.php(656): Code_Snippets\execute_snippet('function my_exc...', 13) #2 /home/ptcondo.org/wp-includes/class-wp-hook.php(308): Code_Snippets\execute_active_snippets('') #3 /home/ptcondo.org/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #4 /home/ptcondo.org/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #5 /home/ptcondo.org/wp-settings.php(486): do_action('plugins_loaded') #6 /home/ptcondo.org/wp-config.php(99): require_once('/home/...') #7 /home/ptcondo.org/wp-load.php(50): require_once('/home/...') #8 /home/ptcondo.org/wp-admin/admin.php(34): require_once('/home/...') #9 {main} thrown in /home/ptcondo.org/wp-content/plugins/code-snippets/php/snippet-ops.php(575) : eval()'d code on line 6
