sound problems

[THE/ILL/WILL]

Hay guys i have been working on some sound scripts, and really have no idea what im doing. Here is my code. Would you guys tell me that im doing wrong? This is the first time i have done any of this kind of stuff so I dont know what even to ask.
////////////////////////////
// Run first time starting map
void OnStart()
{
AddEntityCollideCallback("Player", "doorslam_1","Collidedoorslam", true, -1);
}

void Collidedoorslam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("Room_2", true, true);
}

void ScaryVoice()
{
AddEntityCollideCallback("Player", "Room_2","PlaySoundAtEntity", true, -1);
}

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

{
PlaySoundAtEntity("Player", "amb_hunt01", "Door_2", 0, false);

}

////////////////////////////
// Run when entering map
void OnEnter()
{
if(ScriptDebugOn())
{
GiveItemFromFile("lantern", "lantern.ent");

for(int i=0;i<10;i++) GiveItemFromFile("tinderbox_"+i, "tinderbox.ent");
}
}

////////////////////////////
// Run when leaving map
void OnLeave()
{

}
