Refinery study output not showing

Hello everyone,

I have a working Dynamo script that was originally made for Refinery, but the outputs do not appear in the Study window.

The script was created in Revit 2021, and I’m now trying to update it for Revit 2024. Everything seems fine in Dynamo — I’ve updated all the nodes — but the nodes set to “Is Output” all show up empty when I run a study. I even tried setting a fixed number as an output just to make sure it wasn’t the script logic causing the issue, but even that shows up empty.

Is this a known problem, or can anyone help me find a solution?

The purpose of the script is to find the optimal placement of tower cranes on a construction site. I use Remember nodes in the script so that it can be replicated.
