Ladell,
The calendar as it stands today, is not very useful. In order to show our "date field", I had to create a task in the template that correspond to that, because the calendar shows dates associated with "TASKS" not "DATES" as in a date field.
I only need to show 1 date, where as "due date" for you can be associated with many tasks - really all tasks have a due date. But if you are only trying to track a particular task, then track that task in the calendar.
I'm rambling - let me know if you understand the foundation of what i'm trying to tell you.
