help needed with pager

http://scottishsocialnetworks.org/editor.php http://scottishsocialnetworks.org/editor.phps the pager in this page works except try and choose aberdeen from the area dropdown. You should get 18 answers which is fine except when page 2 is pressed at the bottom the query seems to be scrubbed and it returns the full database. any ideas how I can 'save' the query and not create a new blank query every time the page is slef submitted?
