And if it get's same number again?

pawn Код:

stock GetRandomNumber(maximum,lastnumber)
{
    new i=-1;
    while(i == -1)
    {
        i=random(maximum+1);
        if(i == lastnumber) i = -1;
    }
    return i;
}

I created this stock for you now. Params are obvious. If you want to get new random number between 0 and 100 and it should differ from 56 (example) you would do

pawn Код:

new number = GetRandomNumber(100,56);
