I've always been confused about extracting/referencing data returned in a hash. What's the proper way to pull specific fields/values out of a hash, for example, how do I reference the 'status' field value, or the 'field' value in this hash:

$VAR1 = { 'cookies' => { '_AVESTA_ENVIRONMENT' => 'prod', '_mcid' => '
+1.340667ccb3eb6552450356561ab6bd92.4410ca7570d70e1141356a24d924a2a789
+d1bea2b8a417b761406f755ab1d9ba' }, 'error' => '400 Bad Request', 'con
+tent' => { 'detail' => 'The resource submitted could not be validated
+. For field-specific details, see the \'errors\' array.', 'errors' =>
+ [ { 'message' => 'This value should be of type object.', 'field' => 
+'merge_fields' } ], 'status' => 400, 'title' => 'Invalid Resource', '
+type' => 'http://developer.mailchimp.com/documentation/mailchimp/guid
