Help in date script

[#1]

Hi

I would like to count on rows (SeriesUID) by the following conditions:

(today date - validated date(column1))>7 and column2 is null

This is my script:

count({$<today.date-[Validated.autoCalendar.Date]>{7}>}SeriesUID) and

count({$<Truther1={null}>}SeriesUID)

I got an error in: set modifier expression

I will be glad for help in the script.

Thanks.

Max
