Hello. I have a contact form 7 and i want to descrease value of acf filed by one after succesfull submission. How to do that ?

I am trying something like this –

function my_acf_update_value( $value, $post_id, $field ) {

	        $value  = get_field('custom_field_name', $post_id);

					$value--;

	    return $value;
}

add_action('acf/update_value', 'my_acf_update_value', 10, 3);

add_action('wpcf7_mail_sent', 'my_acf_update_value', 1);
