[SCRIPT] Error at unlocking door with an item

[KingCrimson]

It says:

"FATAL ERROR: main (21,23) : ERR : Expected identifier"

This is a copy of the .hps file:

////////////////////////////
// Run when the map starts
void OnStart()
{
AddEntityCollideCallback("Player", "script_slam", "func_slam", true, 1);
}

void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("door2", true, true);

PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);

PlaySoundAtEntity("", "react_scare", "Player", 0, false);

PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);

GiveSanityDamage(5.0f, true);
}

AddUseItemCallback("", "secret1", "lckd", "unlock", true);

void unlock(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked(lckd, false, true);
PlaySoundAtEntity("", "unlock_door", door, 0, false);
RemoveItem(secret1);
}

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

}

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

}

secret1 = Key name
lckd = Locked door name

PS: I don't know if it might have something to do with the error. But the key you must use, you get it on the level before this one.
