Filter rollup field by created date

[SoMedia]

I have rollup field that sum all the records from a table. I want to limit the sum from all to sum for current month only.

How can I do it?

Hi,
in rollup source table, create formula field IF(MONTH(TODAY())=MONTH({Date Field},'Current')
in rollup settings, put filter according to it.
