I have recently come across a blogpost (https://bim42.com/2016/05/wall-openings-again/) which showed me how to tag a wall opening with the bottom and top elevation.
I´ve done the exact same steps with my project but it does not run correctly.
My question here is where can I find the schedule level and how to work with it in dynamo to get the top elevation?

Thanks for the attention
