Dear Dr. Ruud,
Thanks it works. I change this line into:
my $name = ($query_obj->param('text_field') or ' ');
But I am not sure why I need to add the (or ''). I
see nowhere in CGI.pm talking about it. Can you
explain it in a liitle bit detail? Also what am I
supposed to do if I want results not to appear on the
same page as those in the form page?
Thanks,
Li
