Clearing Excluded / Blocked periods

An excluded (or blocked) period is one you have marked as not being able to contain any lessons.

  Q    I am in the middle of scheduling**, but I want to clear periods that I blanked off / excluded / blocked / made unavailable earlier - how do I do that ?

  A    There are 3 possible answers:

1.
If you blocked them off on the Staff Availability Screen (or the Staff Timetable Screen), so that they are showing as blue cells, then just double-click with your mouse on the cell on the Staff Timetable Screen.

2.
If you blocked them off on the Class Availability Screen (or the Class Timetable Screen), so that they are showing as brown cells, then just double-click with your mouse on the cell on the Class Timetable Screen.

3.
If you blocked off the periods on the School Structure -> Shape Screen (see section B in the Manual), then go to:  Schedule Menu-> Global changes-> Clear all blocked periods

**Note: if you haven't started scheduling, then you can just change these details on their original screens.
