How to: Hash reference using text variable

[Marv]

Let's say you have a hash of hashes and you access one of its values like this

print "$myhash->{ParentKey}->{ChildKey}";

and that actually prints: myValue

But now, you want to store the access path in a text variable like this

$txtvar = "{ParentKey }->{ChildKey}";

and you want to print myValue,

How in the wolrd you do that? :confused: Hope you can help me
