nested hash / openstruct question

Hello,
I am a newbie to Ruby. I am having trouble reading the entries from
nested yaml configuration file. Any help would be highly appreciated.

YAML configuration file:
---
AppName: Record Center
DEV:
- user: test
webServers:
webserver1: wserver1
webserver2: wserver2
appServers:
appserver1: aserver3
appserver2: aserver4
password: blah
QA:
- user: test
webServers:
webserver1: wserver11
webserver2: wserver22
appServers:
appserver1: aserver33
appserver2: aserver44
password: blah

My code uses hash to openstruct code
(http://www.dribin.org/dave/blog/archives/2006/11/17/hashes_t...).
Things work fine when I read the AppName. When I try to read the user /
password or webServers or appServers entry... I am getting the following
exception.

Sorry...I hit the submit button before pasting the actual error message.
recordcentercrawler/rccrawler.rb:30: undefined method `webServers' for
#<Array:0
x2dbc868> (NoMethodError)

Any help would be highly appreciated.

Thanks

Your YAML has arrays under DEV and QA.

Try replacing "-" with " ".
