Passing Pointer objects to Methods

In short, I've created a bank object. Using my CreateBank() method.

 Bank* Program::CreateBank()
    {

        //Creates a new Bank object.

        Bank *bank = new Bank();

        return bank;
    }

Then, when the bank has been successfully created, I basically want to be able to pass it to any other method -- It's next location should be the PopulateBank() method which will fill it with information.

    void Program::PopulateBank(Bank* bank)
    {
        bank->populate();
    }

However, the PopulateBank() method currently cannot be compiled. I have the following error preventing me from doing so:

"A nonstatic member ference must be relative to a specific object"

Here is the code I'm using for my calls:

    void Program::TestBankClass()
    {

        //Creates new bank Object.
        //Populates the bank object.
        //lists customers that were populated with all information.

        Bank* bank = CreateBank();

        PopulateBank(bank);

        ListAllCustomers(bank);

And here's my header file:

class Program
    {

    public:

        static void AccountTester();
        static void TransactionTester();
        static void CreditAccountTester();
        static void TestCustomerClass();
        static void TestBankClass();

        void ListAllCustomers(Bank* bank);
        Bank* Program::CreateBank();
        void PopulateBank(Bank* bank);

    };

Anyone know what I'm doing wrong? or could give me some tips? would really appreciate it!
