pawn Код:

stock GetHighestKiller()
{
    new m;
    for(new i = 0 ; i <= MAX_PLAYERS ; i++)
    {
        if(KillerScore[i] > KillerScore[m])
        {
            return i;
        }
    }
    return -1;
}

Also why you have m variable to be compared ?
When you

pawn Код:

new m;

It'll have "0" as a value.
