as you can see, its not working in my case

When I look at your graph, it seems obvious to me that the second List.GetItemAtIndex node should return an error because there can’t be an item at index 2. To work efficiently with lists, you should unroll your nodes to see what’s in. Here are some indication that could help you:

EDIT: I now saw that your wall is not a curtain wall, I’m sorry. Maybe you can use some of the logic anyway.
