Thanks Eric, I didn't know about the debugger.
When I ran: rails server --debugger I got the error that I needed to
install ruby-debug with 'gem install ruby-debug' but when I did the
error: "Failed to build gem native extension." and then there were a
bunch of errors involving "no member" in RArray and RString. I then
successfully installed ruby-debug-ide19-0.4.12, "but the rails server
--debugger" gave the same error as before. Maybe I need to ask this
in a separate question, but if you know the answer to the problem off-
hand I'd appreciate knowing it.
Thanks,
Barney
