Cant get this function to work (sound)

[flamez3]

void OnStart()
{
SetEntityPlayerInteractCallback("Key_1", "Scary_3_1", true);

}

void Scary_3_1(string &in entity)
{
SetEntityActive("Skull_1", true);
PlaySoundAtEntity("", "21_scream7.snt", "Player", 0, false);
GiveSanityDamage(5.0f, true);
AddTimer("CabinetTimer",0.7, "Scary_3_2");

}

This is so weird cause all the other functions work but not the "PlaySoundAtEntity" , and I have used that script before, in the same map. Does anyone have an idea why it doesnt work?

Did you restart the CS and try again?
