Configurable reports block (plugin)

Hi,

I have tried using the Configurable Reports plugin, however my reports are coming up blank. I am not using the SQL feature, but I did want to use the Courses report.

I would like to set up three reports:

1. Count of all students enrolled in a course in a particular month (i.e. Sep 1 - Sep 31)
2.  Count of all students who have completed the course in a particular month (Sep 1 - Sep 31)
   
3. Total enrolled in the month  (Sep 1 - Sep 31)
4. Total completed in the month (Sep 1 - Sep 31)

Any suggestions would be greatly appreciated.

Thanks

Leticia
