No. You could make a function of the whole thing and say 'return "Blue"'
instead of 'Decision="Blue"'. But here's a neater solution.
function chosen(x) return tonumber(ChooseSetting(x)) end
Decision = (chosen(a) and chosen(b) and chosen(c) and "Blue")
or (chosen(d) and chosen(e) and "Red")
or (chosen(f) and "Yellow") or "Orange
The logical functions do shortcut evalation, so it will skip unnecessary
