Amazing, thanks. I added in a little extra code as I’m using a unique ID for the questions (in case they change the question text):
$question = get_post_meta($post_id, $repeater.'_'.$i.'_'.$subfield, true);
$uid = get_post_meta($post_id, $repeater.'_'.$i.'_'.'uid', true);
$this->choices[$uid] = $question;
Thanks again! Really appreciate you taking the time to look at this.
