for(new i = 0; i < MAX_FURNI; i++)
{
    if(FurniCode[i] == furnic)

        furnic = rand // generate the number again and loop again
        continue;

}

Just generate a new number if it matches and continue to see if it still matches. Or you can keep a variable that increments each time a furniture object is created and save and load it when the server closes / starts.
