Could someone tell me what this means? Im not sure why this isnt working. Heres the error "Modification of a read-only value attempted at line 868 <LIST> line 22". What does the <LIST> line 22 mean? Heres the code: 
# Grabs each district from all_store array
foreach $dist_only (@all_store_info) {
    my @array = split(/ / , $dist_only);
    my $test = @array;
    next if $test < 2;
    $distlist = "$array[1] $array[2] $array[3]";
    push(@dist_list, $distlist);
    #print "$distlist\n";
} 


@dist_list = sort { $a <=> $b } @dist_list;

my %uniq;
undef @uniq{@dist_list};
@dist_list = keys %uniq;
