Hello, this is giving me : sscanf warning: Strings without a length are deprecated, please add a destination size.

            sP[MAX_PLAYER_NAME + 1],
            sV[34 + 1],
            fString[256];
            
            
        if(!(PlayerInfo[playerid][pAdmin] >= 3)) return SCM(playerid, COLOR_GREY,"You are not authorized to use this command");
        if(sscanf(params, "s", sP)) return SendClientMessage(playerid, -1, "USAGE: /createacc [NAME_SURNAME]");
        if(strlen(sP) < 3 || strlen(sV) > MAX_PLAYER_NAME) return SendClientMessage(playerid, -1, "ERROR: Invalid name lenghth");
        new sendername[MAX_PLAYER_NAME], string[256];
        GetPlayerName(playerid, sendername, sizeof(sendername));
        format(fString, sizeof fString, "Users/%s.ini", sP);
        new INI:File = INI_Open(fString);
        INI_SetTag(File, "data");
        INI_WriteInt(File,"Password",udb_hash("changeit"));
        INI_WriteInt(File, "Cash", 0);
        INI_WriteInt(File, "Admin", 0);
        INI_WriteInt(File, "Kills", 1);
        INI_WriteInt(File, "Deaths", 1);
        INI_WriteInt(File, "Skin", 266);
        INI_WriteInt(File, "Logs", 1);
        INI_WriteInt(File, "Banned", 0);
        INI_WriteInt(File, "Crim", 0);
        INI_WriteInt(File, "Pw", 0);
        INI_Close(File);

        SendClientMessage(playerid, -1, "Account created!");
        format(string,sizeof(string), "AdmWarn: Admin[%i] %s has created an account with the name: %s",PlayerInfo[playerid][pAdmin], sendername, sP);
        SendAdminMessage(COLOR_YELLOW, string);
        format(string,sizeof(string),"[%d-%d-%d] AdmWarn: Admin[%i] %s has created an account with the name: %s",GetDay(),GetMonth(),GetYear(),PlayerInfo[playerid][pAdmin],sendername, sP);
        Log("/logs/Accounts.txt",string);
        return 1;
    }

I tryed with this if(sscanf(params, "s[37]", sP)) return SendClientMessage(playerid, -1, "USAGE: /createacc [NAME_SURNAME]");

but then when I do /createacc Test_Test it gives me an error

The command works fine but I want to get rid of the warning.
