hm, it should show at the bottom right when its done parsing. Anyway, you should use list variables as they are the best. A list variable is e.g. {List::%player's uuid%} while a standard variable is e.g. {Standard.%player's uuid%}. The difference is that list variables add to the variable, hence it being a list. While a standard variable just creates an entire now variable, being a pain to change.
(Also 2k lines is alot, also use functions)
