Can’t get a custom template taxonomy page to display

I found this code;

function ftc_flush_rewrites() {
global $wp_rewrite;
$wp_rewrite->flush_rules();
}

function ftc_add_rewrites() {
global $wp_rewrite;
$ftc_new_non_wp_rules = array(
'find/(this)' => '/addit.php?here=$1',
);

$wp_rewrite->non_wp_rules = $ftc_new_non_wp_rules + $wp_rewrite->non_wp_rules;
}

add_action('generate_rewrite_rules', 'ftc_add_rewrites');
add_action('admin_init', 'ftc_flush_rewrites');

in this thread http://wordpress.org/support/topic/writing-wp_rewrite-gtnon_wp_rules-to-htaccess …not sure if that addresses the problem but good luck!
