Hello, I've been trying to figure out/understand how to create hash of hashes from an input file. I want to be able to create references to each element using variables. Not exactly sure how to actually create the hashes from an input file. Here is a small sample of what my data file looks like my actual file contains all my users data:

FullName        : User1
Home Address        : 111 address lane
Phone            : 555-555-5555

FullName        : User2
Home Address        : 222 address lane 2
Phone            : 777-777-7777

Here is the code that I've been playing with so far:

#!/usr/bin/perl
use strict;

my $myfile = $ARGV[0];
open FILE, "<", $myfile || die "No open $!\n";

my %hash;

while (<FILE>)
{
   chomp;
   my ($key, $val) = split /:/;
   $hash{$key} .= exists $hash{$key} ? ",$val" : $val;
}
foreach my $key (keys %hash) { 
    print "$key = $hash{$key}\n";
}

Trying to create groupings name, address, phone using the LABELS on the left side ("FullName", "Home Address", "Phone"). I am trying to use the key $name and print all data for that $name variable. output example:

User:
User1
111 address lane
555-555-5555

User:
User2
222 address lane 2
777-777-7777

This way I can actually map all FullNames to actual names all Phone to Phone number etc.. I tried creating a reference to an anonymous hash, but the problem is not sure how to only store all names all phone# etc in each hash.

$hash{$x}= {
    Name => $name,
    Addr => $address,
    Phone => $phone

Not sure how to go about this any help would be very much appreciated as I am not getting any where here. I can accomplish this using awk/cut but I started to play around with it in Perl and never really used hashes so I thought this would be a great time to learn/try to understand it. Thanks for all the help in advance. FYI:
