Problem with Document Trigger

[NickHoff]

I have the following sheet trigger which works correctly when I leave the sheet and come back to it..

=IF(%ToggleDRGType = 'Facility by DRG','Q4-2015',MaxString({1<CalendarQuarterYearSort = {"$(=Max({1}CalendarQuarterYearSort))"}>}CalendarQuarterYear))

However, if I add a document trigger On Change on the CalendarQuarterYear field with the same logic it doesn't work.  Why is that?

None of my document triggers work in AJAX, but they work on desktop.  Is that what you're having?  I think document level triggers just don't work with AJAX the same way macros don't.
