NP17 Filter problem between dates

[slondono]

Hi guys

Im trying to create a filter en NP17 between two dates, i´ve tried everything

The correct expression is this ">=$(=Num(Today()-7))<=$(=Num(Today()-3))" i already proved in qlik sense, so in NPrinting 17 it doesnt work...ive tried this

and this

and this

But the report result all in blank (when i remove the filter works good)

Any idea?

Thanks to all
