Do it much simpler. Build a test model that is around only this special request. You need for such a test only queues in a 3D model. You logic structure reads values of a table. Those values are responsible to move items out of a storage (Queue) to a different place (Queue). This sounds like a loop structure to move one item after another.

• A for loop structure increments a label value in steps.
• Another loop like structure calls a subflow as often as a value tells it so.
• A while loop structure tests a condition to be true to start a cycle, while inside a comparison value changes within.
• A until loop structure starts a cycle and test at the end a condition to start another cycle or to go on in your logic structure.

If you need assistant to assign label values or increment label values, then you should repeat tutorials in manual about process flow.

If you need support to work with different datatypes and data structures then you find information for this in the manual under Flexscript API classes.

This link goes to the table class. In Manual content tree you find other datatypes and structures to investigate to work with them.
