Help! Does anyone know why my hook doesn't work?

void (*uplevel)(void *instance,int value);
void (*old_levelup)(void *instance);
void levelup(void *instance) {
if (instance != NULL) {
    if (AddLevel) {
        AddLevel = false;
        uplevel(instance, 9999);
  }
}
old_levelup(instance);
}

case:
    AddLevel = true;
break:

bool AddLevel = false;


void (*uplevel)(void *instance, int value);

void (*old_levelup)(void *instance);
void levelup(void *instance) {
if (instance != NULL) {
    if (AddLevel) {
uplevel(instance, 1);
  }
}
old_levelup(instance);
}


uplevel = (void(*)(void *,int))getAbsoluteAddress("libil2cpp.so", 0xA62594);
   HOOK_LIB("libil2cpp.so","0xA64C08", levelup, old_levelup);


   OBFUSCATE("99_CollapseAdd_Toggle_Add Level"),


     case 99:
            AddLevel = boolean;
            break;
