It looks like there is a nesting issue.
Only one event will display per day, when that event title is clicked on, it shows the details, and then shows the link to the second event in the main screen.
In the code, the second event is nested inside the first event, and the element is set to display none. Is this an issue with WP3.5.1, or is it just a typo in the code?
