ERR : Expected ";"

[WALP]

void OnStart()
{
PlayMusic("introtheme.ogg", true, 0.9, 1.0, 1, true)
AddUseItemCallback("", "Key", "Door_2", "UseKeyOnDoor", true);
AddEntityCollideCallback("Player", "Walk_Quest_Area", "GetWalkQuest", true, 1);
AddEntityCollideCallback("Player", "Walk_Quest_Area2", "GetWalkQuest2", true, 1);
AddEntityCollideCallback("Player", "TeleportScript", "NailThatSucker", true, 1);
}

As informed in the headline a ";" is expected, but at the end of PlayMusic you forgot to add one. so:

PlayMusic("introtheme.ogg", true, 0.9, 1.0, 1, true);
