Can someone show step by step how to build the timetable? My master timetable show nothing after completing the tie days to date step.
Alright, I finally got it through, however it seems like the system doesn’t detect the clashes of the same teacher teaching different subject at the same time slot. Or have I missed out something in the set up? 
Hi Tklee,
I suspect it may not detect or prevent clashes to keep the system flexible: with all the possible ways a school could setup their timetables, there may be valid reasons a school needs to have courses & teachers setup that way. In your schools own timetabling though, if the clashes are unintended or unwanted you could perhaps use a query to find these instances (using the Query Builder module from the Extend page).
Hi Sandra,
Thanks for the clarification, I will give it a try using the query. Cheers!
