yet another question ...

I see it is used in a lot of quests to do a setstage ...

but at level 0 is used to make setup() why that and what's for?

Also when I tried to use in my quest

I get


Starting 1 compile threads for 1 files...
Compiling "QF_PROM_HyborianMound_01047909"...
d:\giochi\steam\steamapps\common\skyrim\Data\Scripts\Source\temp\QF_PROM_HyborianMound_01047909.psc(68,0): variable kmyQuest is undefined

why?
