Renderman tractor filter question

Hi all, I am playing around using the renderman tractor within my company. Noob here by the way, but this thread seems to be the only place that I can place my question…

As I am trying to create some filters by using the attributes from the Jobs Pane Info (those in purple wordings)…

Say if I am trying to filter a list of current tasks by the maxActive attributes in which the values is 10, I tried using the ‘Freestyle match = 10’ or ‘Freestyle match == 10’ or ‘Freestyle match like 10’, I am unable to get any of the result displayed despite there are indeed 1-2 tasks that fulfill that condition.

Can anyone point me where I am wrong?
