i'm trying to pull a slice out of a hashref of an arrayref and i'm failing. here's what i have:

print join(',', @{ $uword{ $seen{ $key }[ 1 ] }[ 1 .. $#{ @uword{ $see
+n( $key ) } } ] } );

what perl is telling me is:

Global symbol "$seen" requires explicit package name at ./namevsfield.
+pl line 105.
syntax error at ./namevsfield.pl line 105, near "$seen( "
syntax error at ./namevsfield.pl line 107, near "}"
Execution of ./namevsfield.pl aborted due to compilation errors.

line 105 is above and line 107 closes my for my $key (keys %seen) { loop. these two variables were defined with:

   foreach my $string ( @word ) {
      if ( $uword{ $string }[ 0 ] == 1 ) {
         push @{ $uword{ $string } }, $line;
         next;
      }
      $uword{ $string }[ 0 ] = 1;
      push @{ $uword{ $string } }, $line;
   }

and
   foreach my $string ( @data ) {   # dedupe data and sanity check.
      next if !defined ($string);   # should never be true.
      next if $seen{ $string }[ 0 ] == 1; # check %seen hash / array f
+or dupe
      $seen{ $string }[ 0 ] = 1;    # define hash of array and assign 
+check to it.
      $seen{ $string }[ 1 ] = $key; # add word from line to hash for r
+eference.
   }

where i'm taking out dupes and appending where the data came from to a hashref of the hash. then i need to print out all of the data. i have no issues with posting the code if need be, i just didn't think it necessary. any help would be greatly appreciated. thanks
