Is there a way to get something like this to work?

=SUMIF(Date:Date, >[Last Active Date]1, CHILDREN([Points]1))


Basically Date;Date has dates inserted in the range. 

Points has a point value

I'm trying to get dates that are greater then the Last Active Date, and then add up the total Points if they meet the date & is a children of the parent row.
