blackhornet - The outcome is still the same without the "Obstacle.PickedCount = 0".
But I do understand what your point is. So you mean that the "Pick by comparison - Obstacle.Signature = 'Active'" is the same as "Obsctacle.Signature = 'Active'", that it doesn't
run if the condition is false.
That makes sense since there are 0 instance in the layout that has the Obstacle with Signature = "Active".
Nice. Thanks, I get it now.
