It is unbelievable how much time I waste on trying to get things done what could be done with variables in a minute :( If I find a way to make it work it is a result of duplicate code (a lot more lines than I would need with vars) or a lot partial files.

Right now I'm stuck with this problem for over three hours of reading the docs and trial and error: I have to check if a certain field in a bard is filled OR another field which is not contained in that bard
