1. Depends on what you want. If you just want to keep the program from crashing when outTemp is None, you could use
outTemp is not None and outTemp < 3 3. There's no magic here. If you enable a skin, it will get processed. If you don't, it won't. There is no "default" skin. Look in [StdReport]. It's possible you have more than one skin enabled and they are overwriting each other. On Sun, Nov 22, 2020 at 6:11 AM GBW <gwalki...@gmail.com> wrote: > 1.
