I reviewed your question and we will be using it today on Project Talk, if you would like to join us. Also if you combine your formula into a single field using nested if statements, then you can group on a single field instead of having to use mutiple fields. IIf([Outline Level]=2,"02 – Event",IIf([Outline Level]=3,"03 – Accomplishments",IIf([Outline Level]=4,"04 – Criteria"," ")))
I also eliminated the task name so the grouping will not be unique for each task, you could add that back in if you want but it will display a new group for each task. Hope this helps.
