Problem:
When attempting to create a unit (or topic) plan, you are able to select a unit but the second list box reads 'None available' and the 'Create' button is greyed out.

Cause:
The unit and topic planners require a class to be available and selected before a plan can be generated.

Note. if there are no saved plans, then the third listbox will also read 'None available'

Solution:
From the Main menu, select 'Administration' and create a class.
The second listbox on this panel will now read 'Select a class'.
