That will not work. You build a hash like this:

[0] Perl> %hash = (
              1 => {
                1 => "nothing",
                name => "Shrek",
                event  => "I saw shrek!",
              },
              6 => {
                1 => "nothing",
                name => "Donkey",
                event  => "I saw the donkey!",
                2 => "nothing",
                name => "Fiona",
                event => "I saw Fiona!"
              },
);;

But end up with this:

pp \%hash;;
{
  1 => { 1 => "nothing", event => "I saw shrek!", name => "Shrek" },
  6 => { 1 => "nothing", 2 => "nothing", event => "I saw Fiona!", name
+ => "Fiona" },
}

NOTE: that in the hash key by '6' there is only one 'name', and only one 'event'.

You cannot have duplicate keys in a hash. You need to rethink your data structure.
