Hello all,

So I'm writing another ultra simple, and pretty pointless, learning program. Here is the start of it

#!/usr/bin/perl

use strict;
use warnings;

print "\nMean Average Program\n\nenter values, when done enter 'done'\
+n\n";

my $total = 0;
my @value;

my $control = 1;
while ($control != 0){
  print "Enter a value('done' if finished): ";
  chomp($value[$total] = <>);

  if ($value[$total] eq 'done' || $value[$total] eq 'Done' || $value[$
+total] eq 'DONE'){
    $control = 0;
  }

  $total++;
};
pop(@value);
$total--;

my $mean = 0;
for my $valNum (0 .. $total){
  $mean += $value[$valNum];
}

$mean = $mean / $total;

print "\nThe mean of your values is $mean\n";

The code runs and does the calculations right, but I get an error message in the middle of running in the vien of the title.

the error message points me to this line: $mean += $value[$valNum];

I've tried adding a line before the loop initializing valNum with 0 and got rid of the my in the for loop, and it still said the same thing. I know it's prob something simple, but I'm not seein the prob, need some help please.
