These are still NOVs which you can use as any variable in math formula.

yes, and if I only want to display one nov depending on the selection of the window type? how do I do that ?

Put these NOVs in different dynamic notices and display them conditionally.

ok, i did and it works so far. but i have a question. what do you use the “main formular” field for? I entered a math problem there, but that doesn’t affect the result.

Sorry, I don’t understand your question.
