Well, I've been working on a couple of the issues of concern from reviews. I've added a bit of formatting control, making the map and list appear side by side, and re-arranging the search options along the top. I have also addressed the issue of missing address, city, state, or zip code information by filtering out those events that are missing some key piece of info. It seems to have taken care of the problem we were having with events popping up that were clearly outside the requested range. The final bit of work that I've completed is the separation of event title and venue name for the list of events. I'm still trying to work out how to incorporate date ranges. I have a couple of ideas, but haven't figured out how to work them in just yet. In particular, the javascript calendar widget that I found doesn't seem to like either having two calendars on the same page, or selecting multiple dates on one calendar. I'm still trying to work with this calendar, but if anyone has had a good experience with a javascript calendar I'd really appreciate the web site.
Here is the site for what I've done so far (if it doesn't load or does something funny, that probably means that I'm working on it some more) people.emich.edu/jkeswick/IS449/project/iteration3.html
