Conditional Decide Question

Hello,

I created a decide activity which will push items to a queue called "PickingStation" only when "PickingStation" is empty. I attempted to do this by creating a label called "StationCapacity" which would count how many flowitems was in "PickingStation" with the code

model.find("PickingStation").as(Object).subnodes.length

but it is always returning a value of 0. Is there a better way to determine if there is items in "PickingStation"? I've attempted to set the max limit on the queue named "PickingStation" to 1, but items are still able to be placed into the queue via my process flow. Model attached below

@King-Ki F

I think you what you are looking for is a zone. Here is a tutorial on how to use them to collect statistics, but you can use it to get familiar with them. You can use a zone to limit the number of tokens that enter a part of process flow.
