Why is my custom story not working!?!?!?

[Gamerlord08]

hello users, i am experiencing a problem with my custom story, it says when i boot up, "Unexpected end of file" i am very, VERY new to coding, so i might have a obvious flaw somewhere, but i cannot find it, here it is:

///////////////////////
// Run when entering map
void OnStart()
{
PlayMusic("01_amb_darkness.ogg", true, 1.0f, 0, 0, true);
AddEntityCollideCallBack("Player", "PlayerCollide", MonsterFunction", true, 1);
AddEntityCollideCallBack("Player", "MonsterEnd", true, 1);
}

void MonsterFunction(string &in asParent, string &in asChild, int alstate);
{
SetEntityActive("servant_grunt_1", true);
AddEnemyPatrolNode("servant_Grunt_1", "PathNodeArea_1", 2, "");
AddEnemyPatrolNode("servant_Grunt_1", "PathNodeArea_2", 0, "");
AddEnemyPatrolNode("servant_Grunt_1", "PathNodeArea_3", 0, "");
}
//////////////////////
// Run when leaving map
void OnLeave()

if you can, please help me, i just want to make a little custom story is all.
