Item pickup trigger sound help

[Xallikk]

When I run the game, it crashes and says expected data type. I'm pretty sure my code is wrong, I'll put it here:

void OnStart()
{

AddUseItemCallback("", "Key", "Door", "UseKeyOnDoor", true);
AddUseItemCallback("OpenDoor", "LevelKey1", "LevelDoor1", "UseKeyOnLevelDoor", true);
AddEntityCollideCallback("Player", "SpawnScare", "SoundCheck2", true, 1);
AddEntityCollideCallback("Player", "OpenScare", "SoundCheck", true, 1);
SetEntityCallbackFunc("Key", PickUp);
}



void PickUp("Key", "OnPickup")
{
PlaySoundAtEntity("pickupsound", "21_screams.snt", "PickupSound", 0.01f, false);
}


void SoundCheck2(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("ambientsound", "ambience_wind_eerie.snt", "SpawnScare", 0.01f, true);
}

void SoundCheck(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("scaresound", "notice.snt", "Player", 0.01f, false);
}

void UseKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked(asEntity, false, true);
PlaySoundAtEntity("", "unlock_door.snt", asEntity, 0, false);
RemoveItem(asItem);
}

void UseKeyOnLevelDoor(string &in asItem, string &in asEntity)
{

SetLevelDoorLocked(asEntity, false);
PlaySoundAtEntity("", "unlock_door.snt", asEntity, 0, false);
RemoveItem(asItem);
}
void OnLeave()
{
SetupLoadScreen("Loading", "LoadScreen1", 0, "LoadingScreen1.jpg");
}
