[SCRIPT] AddUseItem Callback Not Working

[dailycreepypasta]

To my luck, something else didn't work. I have a crowbar item in one of my maps named "Crowbar". I have a script that requires the item to function properly. So, while testing the mod I got the crowbar and went to the level with the script. The script isn't working for me! Here's the script I'm using:

PHP Code: (Select All)

void OnStart()
{
        AddUseItemCallback("", "Crowbar", "Door", "UseCrowbarOnDoor", true);
}

void UseCrowbarOnDoor(string &in asItem, string &in asEntity)
{
        RemoveItem(asItem);
        PlaySoundAtEntity("", "player_crouch.snt", "Player", 0.05, false);
        AddTimer(asEntity, 0.2, "TimerPlaceCrowbar");
}
 
void TimerPlaceCrowbar(string &in asTimer)
{
        SetEntityActive("Joint", true);
        PlaySoundAtEntity("", "puzzle_place_jar.snt", asTimer, 0, false);
}
 
void BreakDoor(string &in asParent, string &in asChild, int alState)
{
        SetEntityActive("Joint", false);
        SetEntityActive("Broken", true);
 
        SetSwingDoorLocked("Door", false, false);
        SetSwingDoorClosed("Door", false, false);
        SetSwingDoorDisableAutoClose("Door", true);
 
        AddPropImpulse("Door", 0, 0, 3, "world");
 
        CreateParticleSystemAtEntity("", "ps_hit_wood.ps", "AreaEffect", false);
        PlaySoundAtEntity("", "break_wood_metal", "AreaEffect", 0, false);
 
        GiveSanityBoostSmall();
 
        PlayMusic("10_puzzle01.ogg", false, 0.7, 0.1, 10, false);
 
        AddTimer("", 0.1, "TimerPushDoor");
}
 
void TimerPushDoor(string &in asTimer)
{
        AddPropImpulse("Door", -4, 2, 1, "world");
        AddTimer("", 1.1, "TimerDoorCanClose");
}
 
void TimerDoorCanClose(string &in asTimer)
{
        SetSwingDoorDisableAutoClose("Door", false);
} 


I made sure that the names match and that the casing is the same, and I don't use the crowbar in any script except for one to set an entity inactive. What could be the problem?
