Perhaps I have keys and values backwards. Parker and Bowen would be from the file, and they'd be the keys. I added the san as the value because the way I understand a hash is that it's a pair. If Parker is read in, it would need something to pair with, I just chose san semi-arbitrarily. It could have just as well been foobar, or valuePlaceHolder. The important thing is the hash name, %SAN, and the names to read in, ie, Parker, Bowen etc. san, as the value, is not important, it's just what I thought I'd need to complete the pair. __________________________________ Do you Yahoo!?
