[[XST]O_x]

pawn Код:

GetPlayersOnServer()
{
    new count;
    for(new x=0; x< MAX_PLAYERS; x++)
    {
        if(IsPlayerConnected(x))
        {
            count++;
        }
    }
    return count;
}

I don't see how this is going to work. You're not giving 'count' any value, and then you're actually doing:
count = count+1 (count++), but count doesn't have any value, it contains junk.
Just assign a value to count while defining it:

new count = 0;
