Okay I'm trying to nest music but I keep getting an error. I'm putting the music list in a character sheet named Music for easy compartmentalization. TypeError: Cannot read property 'substring' of undefined Here is my test macro. ?{Music|Victory,%{Music|Victory}|Defeat,%{Music,Defeat}|} !Roll20AM --play& #44; & #124; Victory by Rauros92 !Roll20AM --play& #44; & #124; Defeat - D&D by JohnCesario What am I missing here?
