The_excerpt - by acuariopro - on WordPress WooCommerce support

Hello there,

I´m trying to dysplay the excerpt instead of the content on a category but the excerpt lenght is set to “35” (I need more) and when I try to declare it on my child theme does not work

I find on the parent theme:

// **********************************************************************// 
// ! Set exerpt 
// **********************************************************************//
function etheme_excerpt_length( $length ) {
    return 35;
}

add_filter( 'excerpt_length', 'etheme_excerpt_length', 999 );

function etheme_excerpt_more( $more ) {
    return '...';
}

add_filter('excerpt_more', 'etheme_excerpt_more');

How I should declare it on my child theme to make work it on my theme?.

I was trying with:

if ( ! function_exists( 'etheme_excerpt_length' ) ) {
    function etheme_excerpt_length() {
        return 350;
    }
}

Blessings.
