Okay, first off, you can't do this:

pawn Код:

array[index][cell] = string;

You need to use format:

pawn Код:

format(array, array_size, input); 
format(Businesses[Player[playerid][Business]][bName], 16, Name); // in your case

Second of all, you looked for an optional string but you didn't use it at all.

I suggest you to use sscanf ONLY if you have to look for more than two parameters in a command.

Example:
/mycommand [playerid] // 1 parameter
/mycommand [playerid] [something] // 2 parameters
/mycommand [playerid] [something] [something else] // more than 2 params

If you don't have a second parameter, use "params" as an everything.

pawn Код:

strval(params) // same as sscanf(params, "d", variable);
format(string, sizeof(string), "%s", params); // instead of using sscanf + new non-used string

I think you're using zcmd, this might be useful for you:

pawn Код:

command(businessname, playerid, params[])
{
    new
        string[57];
        
    if(isnull(params)) return SendClientMessage(playerid, WHITE, "SYNTAX: /businessname [new name]");
    else if(strlen(params) < 2 || strelen(params) > 15) return SendClientMessage(playerid, WHITE, "The name has to be between 2 and 15 characters long.");
    else if(strfind(params, "~", true) != -1) return SendClientMessage(playerid, WHITE, "You may not use the '~' character.");
    format(string, sizeof(string), "You have changed your business name to %s.", params);
    SendClientMessage(playerid, WHITE, string);
    SaveBusiness(Player[playerid][Business]);
    Update3DTextLabelText(BIZ1, ORANGE, params); 
    Update3DTextLabelText(BIZ2, ORANGE, params); 
    Update3DTextLabelText(BIZ3, ORANGE, params); 
    format(Businesses[Player[playerid][Business]][bName], 16, params);
    return 1;
}

By the way: If you decide to use sscanf, this is the way:

pawn Код:

if(sscanf(params, "s", Name)) // I'm not sure about the "s", it is "s[size]" in sscanf 2.0...
{
    // syntax message
}
