Hi all.

I'm writing a small opinion poll using perl/cgi and it appears I need a little assistance. See below for code:

#!c:\perl\bin\perl.exe -wT

use strict;
use CGI qw(:standard);

my $line;
my %survey;

print header;

open( FH, ">>psy.txt") or die "Error : $!\n";

foreach my $key( param() ) {
  print FH param($key), "\n";
}

close FH;

open( FH, "<psy.txt" ) or die "Error : $!\n";

while( $line = <FH> ) {
  $survey{$line}++;
}

foreach my $key ( keys %survey ) {

  print table(Tr(td( { -width => "$survey{$key}",
                 -height => "30", -bgcolor => "red" } ) ) ), br;
}

close FH;

The HTML form consists of 15 questions. Each question can be answered via one of four radio buttons. In an attempt to simplify the design aspects, I followed davido's advice and used unique 'id' numbers (starting with 1 and ending with 60). Question 1 is 1..4, question 2 is 5..8, etc. These are written to a small text file then placed into a hash in order to generate a small histogram (via CGI.pm). I'd like to display the output in the following manner:

• Each form question in a table header. In a table row below it, how many responses (integer) and a graphical bar representing this quantity.

Note:This is *not* a homework assignment. It is a favor for a psychology professor.

Thanks,
-Katie.
