EXISTS filter on projects with hour entries that have $0 Actual Cost

Hi WF Community,

I've been reading over Tony Messam's Leap presentation slides in an attempt to try and create the following project filter:

• Projects that have hour entries that have $0 in the hour's Actual Cost field

I have this so far, but it error's out:

EXISTS:1:$$OBJCODE=HOUR

EXISTS:1:ID=FIELD:projectID

EXISTS:1:actualCost=0

Anyone have an idea where I'm wrong?

Thanks.

Nick
