Change:
  $agent=$HTTP_USER_AGENT;

to:
  $agent=$_SERVER['HTTP_USER_AGENT'];

and that should do the trick.  From first thought, this seems like a
register_globals problem, but maybe it's track_vars or variable_order
or something.  Can't remember off the top.  Do a phpinfo(); to confirm
that that var is actually getting created as well.
