I am attempting to find the average of an array with this 

#usr/bin/perl

use strict;
use warnings;
use List::Util qw(sum);

open IN, '<',"part4.csv" or die "can't open input file 'part4.csv': $!
+\n";

my $x;
my @windsordigits;

foreach $x (<IN>){
  @windsordigits = ($x =~ /WINDSOR\sRIVERSIDE.*(\d\d?)/);
  print "@windsordigits\n";


}
my $average = sum(@windsordigits) / @windsordigits;
print "$average";

close IN;

The issue I am having is that I am getting the "Illegal division by zero line 17, <IN> line 41. The regex only matches line 2-14. I am guessing this issue is occurring because the regex is reading all the way to line 41. Another issue I am having is that when I print out the values it is only printing the first digit and not the second. Am I on the right track here as far as the first issue? And if so is there a way to use the regex on a range of lines so that it doesn't run all the way to line 41. Here is a line from the file I am running it on.
