CFDB Search form shows all entries

Search form doesnt appear to work.
On opening page, it just shows what is in the database – search part doesnt work.
<form action=”” method=”POST”>Job Title<input type=”text” name=”Job Title” />
<input type=”submit” /></form>[cfdb-datatable form=”Application” filter=”Job Title~~/.*$_POST(Job Title).*/i&&first-name~~/.*$_POST(first-name).*/i”? “]

The page I need help with: [log in to see the link]
