Events+ functionality

My project is for a church website that also incorporates a school. I need to easily distinguish church events from school events, as well as sub-categories of each. These events would be publicly viewable on the main site.

Also, I am using BuddyPress along with Courseware for the middle school teachers and students to have private mini-communities with their groups. I want teachers to be able to post class events that are viewable only by that private class group, and I want students to be able to access that group’s calendar from within the BuddyPress group page.

I am having trouble viewing any event list anywhere. On my events page, it is blank. When I click on Events within a group, I am taken to a “Page Not Found” page.
