conditional statement to verify range provided by #define(d) integers in header for transaction module (.cpp)

First time posting on stackoverflow. I am not sure if the question is clear enough so I will try to explain the problem and provide my code as well.

I am guessing my problem is some issue that has to do with the conditional if statements that I have created in the definition of the member functions that are mentioned in the header. The header has #define statements that have integer values for MIN and MAX for integer variables that will be accepted from input of a user. I cannot seem to be able to validate the number from the input provided. I have run a test with checkvalues issued before and after conditional statement and they seem to be verified no matter what is entered. I had all the conditions in one if statement as well if that makes any difference.

The following is code for a simple accounting app it contains a header and transaction(.cpp) module and main.cpp:

// BTP200 Workshop 2: Compound types and privacy MAIN.CPP

#include <iostream>
#include "AccountNumber.hpp"

using namespace std;
using namespace sict;

int main()
{
    AccountNumber myNumber;
    char name[41];
    int bankCode;
    int branchCode;
    int accNumber;

    cout << "Bank account app" << endl <<
    "===================" << endl << endl;
    cout << "Please enter your name: ";
    cin >> name;
    myNumber.setName(name);
    cout << "please enter your bank account, branch code" <<
    ", and account number as follows:" << endl << "999 999 99999: ";

    do
    {
        cin >> bankCode >> branchCode >> accNumber;
        myNumber.setAccountNumber(bankCode, branchCode, accNumber);
        myNumber.display();
    } while(!myNumber.isValid() && cout << "Invalid account number, (999 999 99999), try again: ");

    cout << "Thank you!" << endl;

    return 0;
}
