syntax issue in set analysis

[toddbuss]

Can anyone tell me why this set analysis works:

Count( {$<ReportDate={"$(=(Max(ReportDate)))"}>*<[Inpatient Bed]={"Inpatient"}>}[Bed ID])

and this one doesn't?:

Count( {$<ReportDate={"$(=(Max(ReportDate)-3))"}>*<[Inpatient Bed]={"Inpatient"}>}[Bed ID])

The Qlik syntax is a necessary evil...but very evil.

Thanks.

Thanks to all.

After toying with the formula for a bit, I discovered that the problem on my end was the date format has to be:  'MM,DD,YYYY' .  Everything is working now.
