I can't seem to get my functions to work for changing the excerpt_more filter of the Twenty Eleven parent theme.

I suspect it might actually be add_action( 'after_setup_theme', 'twentyeleven_setup' ); that's the problem, but I've even tried remove_filter( 'excerpt_more', 'twentyeleven_auto_excerpt_more' ) to get rid Twenty Eleven's function and still my functions aren't changing anything...

Can you help?

Here's the functions.php code in full:

Here's the functions I've added to /mychildtheme/functions.php

function clientname_continue_reading_link() {
    return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Read more... <span class="meta-nav">&rarr;</span>', 'clientname' ) . '</a>';
}
function clientname_auto_excerpt_more( $more ) {
    return ' &hellip;' . clientname_continue_reading_link();
}
add_filter( 'excerpt_more', 'clientname_auto_excerpt_more' );

Thanks,
