Help! Keys

[Victor]

I think I'm cursed... I've done EVERYTHING the guy in this tutorial did: http://www.youtube.com/watch?v=T4k5ILstUxc
But I can't make the fridgin' key work in the fudgin' door! Look at the .hps script:

////////////////////////////
// Run first time starting map
void onStart()
{
AddUseItemCallback("", "key", "door", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("door", false, true);
PlaySoundAtEntity("", "unlock_door", "door", 0, false);
RemoveItem("key");
}

////////////////////////////
// Run when entering map
void OnEnter()
{

}

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

}

Did you find anything? Please help! This is my 483764327846823th try on this, and the key doesn't appear to like the door.
