getting subjects out

[Jackie Shieh]

Hi,

I would like to get data out of topical subjects (650s),
but only the ones that with a 2nd indicator of 0 or 2.
With this script,

my @f650 = $record->field('650');

##
foreach my $f650 (@f650) {
   if ( $f650 and $650->indicator(2) = [02] ) {
      print OUT "650: ",  $f650->as_string(), "\n";
     }
  }


it returns an error: "Can't call method "indicator" on an undefined
value."

What am I doing wrong?!  Thanks for your help!!
