[SPOILER] Error While adding music to area Please HELP

[Greven]

Try putting 01_paper_self in quotation marks like this:
PlayMusic("01_paper_self", true, 5, 0, 0, true);
Also at AddCombineCallback("Player", "Music1", "StartMusic", "true", "0)";
Remove the marks at the 0 like this:
AddCombineCallback("Player", "Music1", "StartMusic", "true", 0);
