I just went through the challenge and I have 2 observations:

1) Make sure on your bottom line, you include the arguments needed to call the pagination function, so:

$pagination = pagination($total_pages, $current_page, $section, $search)

2) For some reason, the final line of the function still need to be an echo statement instead of a return statement to pass the challenge. I dunno about that one, but that's what passed the quiz! So instead of return $pagination:

echo $pagination
