tutorial on path nodes needed!!

[willochill]

well according to that tutorial i did everything rite, but my monster still just stands there not going on any path. i have the pathnodes set up in the map and everything, and i double checked to make sure all my node names in the script matched up with the ones in the map. i posted my script below, what am i doing wrong?
void OnStart()
{
AddEntityCollideCallback("Player", "AreaActivateGrunt", "Func01", false, 1);
AddEntityCollideCallback("servant_grunt_1", "AreaDisableGrunt", "Func02", false, 1);
AddUseItemCallback("", "studykey", "mansion_3", "UnlockStudyHallway", true);
PlayMusic("00_creak.ogg", true, 1.0f, 0, 0, true);
}
void Func01(string &in asParent, string &in asChild, int alState)
{
if (HasItem("lantern_1") == true)
{
SetEntityActive("servant_grunt_1", true);
RemoveEntityCollideCallback("Player", "AreaActivateGrunt"); return;
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_1", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_3", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_6", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_7", 4.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_8", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_9", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_10", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_11", 2.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_12", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_13", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_14", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_15", 2.0f, "");

void Func02(string &in asParent, string &in asChild, int alState)
{

void UnlockStudyHallway(string &in asItem, string &in asEntity)
