in reply to Confused about accessing hashes

First, your $VAR1 is a reference to a hash with only one key, so
$VAR1->{ETPT}
is needed. This one is another reference to another hash with only the key 'SERVER', so
$VAR1->{ETPT}{SERVER}
Now, this is a reference to an array. You want to get all responses...
$VAR1->{ETPT}{SERVER}[0]{RESPONSE} # First element of the array $VAR1->{ETPT}{SERVER}[1]{RESPONSE} # Second element of the array
Probably you want to go for each element of the array like this:
for (@{$VAR1->{ETPT}{SERVER}}) { # here $_->{RESPONSE} is each response of the array }
Hope this helps.
