John looks over the project template he has created. The minus sign (-) indicates a due date before or after the project's post date. The asterisk (*) idicates an item due on the same date. Does this look like the requirements for John's project? Lets look:
 
 
 
 
 
 

1) Call two weeks in advance to schedule the meeting
2) Call five days in advance to confirm the meeting
3) Reserve a meeting room three days before the meeting
4) Attend the meeting
5) Make a courtesy call two days after the meeting

Looks like it! Now lets see if it works...
