Switch this expression to not be influenced by selections

[jeckstein]

I have the following expression

          Count ({<MonthYear = {'$(=Max(MonthYear))'} >} OrderID)

I just want it to not be influenced by any selection I make.

Thanks,

Jimmy

May be this:

Count({1<MonthYear = {'$(=Max({1}MonthYear))'} >} OrderID)
