in reply to Can't use string as an ARRAY ref

$princ is an AoA, an array whose elements are array refs. You are passing one of those array refs to add_more, which you store as $data. However, $data->[0] is a scalar, not an array ref, hence the error message.

    I know, I just can't think on how to fix it.

      It looks like you might be trying to construct a table, possibly in HTML. I would suggest looking into the CPAN modules for that purpose. They will dictate your data structure, at least to an extent.

      Otherwise, what do you want the output to look like?

        Its actually PDF.
        use PDF::API2;
use PDF::Table;

        The issue is in the "for loop", cause if I just pass something like this out side of the "for loop" it goes wel:

         my $extra_data = $data->{$num}{extra};
 unshift @$extra_data,["City", "Street", "ZIP"];

        I even tried passing this:
        add_more( data => $type->[$i], );
        as:
        add_more(data => @{ $type->[$i] }, );

        Course, it didn't work!
