mmm.. the ol' undef value in a hash def, eh?

this should fix it for you...

my $place = seewhatsthere(
  data     => param('place') || '',
  field    => 'Place',
);

Update: Thanks duff! (lightbulb appears mystically above J's head) ..scary how you can go in completely the wrong direction and end up where you need to be..

    Well, it's not an undef as his code would have worked properly in the first place; it's an empty list. But yes, || is another way to force a scalar context on param() such that it does the right thing when asked to return a multi-valued parameter. In fact, I like that method quite a bit :-)
