[SCRIPT] Multiple Keys

[BadCoverMan]

Hello, I had just one key and everything was fine. Then when I tried to have a second key and second locked door, neither of them worked anymore. Here's the script. Any help would be much appreciated. I'm very new to scripting as well so I apologize if it's a really stupid mistake.

Spoiler below!

////////////////////////////
// Run when entering map
void OnEnter()
{
AddUseItemCallback("", "LockedDoorKey1", "LockedDoor_1", "UsedLockedDoorKey1", true);
}

void UsedLockedDoorKey1(string &in asItem, string &in asEntity)
{
AddUseItemCallback("", "SecondFloorKey", "LockedDoor_2", "UsedSecondFloorKey", true);
}

void UsedSecondFloorKey(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("LockedDoor_1", false, true);
PlaySoundAtEntity("", "unlock_door", "LockedDoor_1", 0, false);
RemoveItem("LockedDoorKey1");

SetSwingDoorLocked("LockedDoor_2", false, true);
PlaySoundAtEntity("", "unlock_door", "LockedDoor_2", 0, false);
RemoveItem("SecondFloorKey");
}
