Can someone see if this works in 7?
In 6.5 formulae worked differntly.....

Recurring appointments using formula.

I want an event to occur on the last working (monday-saturday) every month

The formula I've used is

Last(mon:sat) or (Last-1(mon:sat))

It works unless the last day of the month is a Sunday, even though I've allowed Sunday to be a working day.

So 2009 it works for all except May
2010 it works for all except Jan, Feb, October.

Bug? Or bad formula?
How else should I do it?
