Quick Question about level doors.

[A Tricky Carnie]

Hi, I'm working on a Custom Story (Suprise!) and I have a locked Level door and I want to make sure my script is correct, so the door can be unlocked, so here it is:

////////////////////////////
// Run when entering map
void OnEnter()
{
AddUseItemCallback("", "key_2", "mansion_1", "KeyOnDoor", true);
AddUseItemCallback("", "key_3", "level_celler_1", "KeyOnDoor", true);
}
void KeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("mansion_1", false, true);
PlaySoundAtEntity("", "unlock_door", "mansion_1", 0, false);
RemoveItem("key_2");

}
void SetLevelDoorLocked(string& asName, bool abLocked)
{
SetLevelDoorLocked("level_celler_1", false, true);
PlaySoundAtEntity("", "unlock_door", "level_celler_1", 0, false);
RemoveItem("Key_3");
}
////////////////////////////
// Run when leaving map
void OnLeave()
{

}

And on a somewhat related note, how do I name a level door, and how do I set text for when any kind of door is locked?

Thanks in advance
