[Plugin: Widget Logic] parent and all of it's childs and grand kids

do you have some misplaced quote marks there or is that how your code looks?

anyway, if you look up what get_post_ancestors does https://codex.www.ads-software.com/Function_Reference/get_post_ancestors you’ll see it returns an array of IDs. so pain-center or ‘pain-center’, the slug is no use to match with in_array. find the ID of the page and use that integer instead. That should do you.
