The first thing to do, is add the code from the employment page that produces the download links. This will give us an idea of where the download is coming from in the website.
Right now it looks like the problem is the download link itself; all the links simply point to the employment page with a hashtag but no variable after the hashtag. So, unless a form is supposed to submit the data onclick (which is unlikely in the extreme), then the download URLs are incorrect.
So add the code from the employment page that displays the download links and we can go from there.
The problem is definitely the link on the employment page. I suspect that a file being included has been moved or modified.
include("../Functions.inc"); is still in that path relative to the employment page (i.e. one folder up from the employment page).
So change this line on the employment page:
print("<img src=\"../media/hr450.gif\"/><br><a href=\"../Download.php?ID=".$line['URL']."\" target=\"_blank\">".$line['URL']."</a>");
I hope this helps.
