Need help with scripts

[NumsefisK]

Nothing I've done seems to work.

I'll put in my .hps and .lang file below.

////////////////////////////
// Run first time starting map
void OnStart()
{
AddUseItemCallback("", "Bedroom_Key", "Bedroom_Door", "UsedKeyOnDoor", true);
}

{
SetEntityCallbackFunc("Name_of_item", "OnPickup");
}

void OnPickup(string &in asEntity, string &in type)
{
SetEntityActive("grunt_01", true);
}
///////////////////////////////////
//Run when entering map
void OnEnter()
{

}


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

}

The monster doesn't seem to spawn, and the key doesn't work with the door, nor does the key have any name or text attached to it in-game.

The note does not have any name it is just a blank piece of paper when i pick it up in-game.

I saw someone else put the key thing in the .lang file too, but I'm a little confused now.
