I hope I answered your questions in class. Email me if you need further help, and if so let me know exactly what you are doing to access your page. Wait a minute. That's circular. If you're seeing this then you will have accessed the page alrealy. I'll email you the first part of this response.
I am sorry but I have still
been unable to log-in with my access code. If you could send
me an email with directions, I would greatly appreciate it,
and I apologize for any inconvenience.
I also wanted to ask you if it matters which set of data is
specified as y and t? Should the problem work out even if
you were to change which column is y or t?
