Multi-demensional, multi-key hash : Help :(

[Jason Normandin]

Hey Group

I am new to hashes, so please be kind : )

I am trying to create a hash of hash's with the following characteristics:

1. The outer hash has a unique key called $ELEMENT
2. The value of the outer hash is a key to the innner hash called $DATE
3. The value of the inner hash is a value called $ERROR
I need to loop through some data which has multipe $DATE and $ERROR entries
per $ELEMENT and add them to the $ELEMENT hash based on the $ELEMENT value.
Eg. Element Fred would have multiple DATE entries. Each date would have one
error.
I then need to iterate through the hash and display the element name( only
once if possible ), each timestamp and error.
Ex.

ELEMENT DATE            ERROR
jason           Jun 1, 2003     No Data
                Jun 4,2003      No Response
                July 1,2003     No Data
fred            Jan 2, 2002     No Response
                Jany 4,2002     Illegal value
....
..
This is just a dummy example. The real error types range and are unique.

Can anyone help with my constructing such a hash ?

I tried the following, which sucessfully creates the outerhash, but only
populates one value for each date, error pair:
	$snmpErr{$ELEMENT}= 
	{
		name => $ELEMENT,
		date => $DATE,
		error => $ERROR
	};

I then loop through via:

	foreach my $entry (keys %snmpErr)      	
	{
     		$el = $snmpErr{$entry}{name};	
     		$ts = $snmpErr{$entry}->{date};   
		$er = $snmpErr{$entry}->{error};
	}

How far off am I ? : )

Thanks for the help all !!
