Help! Revit Generative Design doesn't display any geometry

Hi, I’ve been working on a script that randomly distribute a family inside floor boundary. I’ve been able to achieve that in dynamo but when i tried to run the script in generative design. it wouldn’t show any results. I made sure to use remember nodes everywhere and assign inputs/outputs…etc.
I don’t know what I am doing wrong. any suggestions please? I am still a beginner in dynamo.

I am working on revit 23, and i have installed the latest updates.
also the screenshot in dynamo has a few errors, but that is because I exported the image from a different device. the one I was working on has the issues/warnings resolved.

after running the study in 2024, I got pictures but they’re all identical and this is not the right floor boundary. I bet it’s from the remember node.

Hard to help without the dataset and graph. It might be a mobile phone thing but your Imgur link is too pixelated for me to read the graph.

Sorry about that. This is the dynamo file with the dependencies and the revit file
And a pdf for the image
