The hist.js file is corrupted. It looks like the code that parses the information from the calendar site and renders it into a javascript array is not working properly. The data on the calendar site does not appear to have changed since last year, but Alvin says he has not altered the code on the page. I tested the code that generates the list of courses from the calendar and that is working. Tomorrow I will test the code that generates the details for each course on that list - that is where the problem lies I suspect. Martin helped find a stupid bug (missing dollar sign) in my debug code which was confusing issues.
