Hi

I have fields targetdate ,opendate,issue ID and status.

I need set expression for below requirement.

count the issue id when targetdate >= opendate and status is open.

I am writing the below expression but it is not working properly.

Count({<[ Target date]>= [opendate ],Status={'Open'}>}distinct Issue ID)

  Thanks.
