Attempted to read/write array element at negative index -1

[Рустик]

Привет всем. Мне нужна помощь.
Выходят такие ошибки:

[02:00:04] [debug] Run time error 4: "Array index out of bounds"
[02:00:04] [debug] Attempted to read/write array element at negative index -1
[02:00:04] [debug] AMX backtrace:
[02:00:04] [debug] #0 0033b52c in public OnPlayerKeyStateChange (playerid=1, newkeys=1, oldkeys=0) :53437

Строка, где ошибка:

if (CarsInfo[vehicleid-1][vNeon] == 0)  - Вот тут и выходит{
        DestroyObject(neons[vehicleid][0]);
                                DestroyObject(neons[vehicleid][1]);
                                neons[vehicleid][0] = -1;
                                neons[vehicleid][1] = -1;
