Thanks for your interest in my work! The note tag only accepts simple number values. So this won't work. NaN, stands for Not a Number because that's what the note tag value was expecting.
Yes, I know what 'NaN' means. Just glad that's all it does is return that instead of crashing. So, I can't even plug in a variable? Hm. This definitely throws a wrench into things... Ah, well...
