Hello you've helped me in the past and I am stuck again. Another newbie trying something new. I've created an html form and a cgi application to process the data a user will enter on this form. Being new to gaining input through a cgi form, I am getting the "use of an unititialized value" error on each line of with the print DATA command. From what I can tell, the variables are being passed from the html form to the script just fine. Before I put the CGI into use I ran it from the command line by typing this for example:

./thinner.cgi date=01/01/05 Goal_Weight=247 weight=265

and I get the error on each line that I use as a scalar for the inputed values. Below is the code, its real simple, and works if I run it from the command line using <STDIN> as my variables. Am I passing the variables into the code incorrectly? Please help I've been racking my brain and turning through every book I know to figure this out. Here is the code, the file paths are not the actual ones, but that should not matter.

#!/usr/bin/perl -w
use strict;

my $dfile = "/stuff/stuff/contest/me/td";
my $wfile = "/stuff/stuff/contest/me /tw";
my $gfile = "/stuff/stuff/contest/me /tg";
my %input;
my $input;
my $wt=$input{'weight'};
my $d=$input{'date'};
my $g=$input{'Goal_Weight'};

open (DATA,">$gfile") or die "File cannot be opened $!\n";
        print DATA "$g";
        close (DATA);
open (DATA,">>$wfile") or die "File cannot be opened $!\n";
        print DATA "$wt\n";
        close (DATA);
open (DATA,">>$dfile") or die "File cannot be opened $!\n";
    print DATA "$d\n";
    close (DATA);
