Assign token label based on the label value of a flow item in a container

There is a label named 'Type' on a flowitem box, which is on a container pallet. I want to assign the box label 'Type' to a label on a token in process flow, where a token is created when the pallet enters a queue. Therefore the assigned 'item' on the token is the pallet. I tried accessing the box's label using the subnodes method in order to get the label value on the pallet:

item.subnodes[1].Type

However, I get the following error:

FlexScript exception: cannot access subnodes property on non-treenode Variant

How do I go about assigning a label value to a token, in process flow, from a value of a label on a box on top of a pallet?

AssignTokenLabelFromBoxLabelOnPallet.fsm

FlexSim 23.1.1

Hi @IceAgeSimultor,

To access the box's label, you should type "token.item.subnodes[1].Type" instead of "item.subnodes[1].Type"

This is because the "Assign Label" activity cannot access the item directly. You need to first reference the token, which contains the label "item," which references the pallet.
